The cheetah is one of the fastest-accelerating animals, because it can go from rest to 27 m/s (about 60 mi/h) in 4.0 s. If its mass is 110 kg, determine the average power developed by the cheetah during the acceleration phase of its motion. Express your answer in
(a) watts
(b) horsepower.
Answers
Answer:
A. 10023.75 Watts
B. 13.44 horse power
Explanation:
A. Determination of the power in Watts.
We'll begin by calculating the energy of the cheetah. This can be obtained as follow
Velocity (v) = 27 m/s
Mass (m) = 110 kg
Kinetic energy (KE) =?
KE = ½mv²
KE = ½ × 110 × 27²
KE = 55 × 729
KE = 40095 J
Finally, we shall determine the power in Watts. This can be obtained as follow:
Kinetic energy (KE) = 40095 J
Time (t) = 4 s
Power (P) =?
Power = Energy /time
Power = 40095 / 4
Power = 10023.75 Watts
B. Determination of the power in horse power.
Power in Watts = 10023.75 Watts
Power in horse power =?
Recall:
746 Watts = 1 hp
Therefore,
10023.75 Watts = 10023.75 / 746
10023.75 Watts = 13.44 hp
Therefore, the power in horse power is 13.44 hp
A wave travels at 1,500 m/s with a frequency of 5 hertz. What is its wavelength?
Answers
Answer:
λ = 300 m
Explanation:
We are given;
Speed; v = 1500 m/s
Frequency; f = 5 Hz.
Formula for wavelength is given by;
λ = v/f
Plugging in the relevant values;
λ = 1500/5
λ = 300 m
The wavelength of the wave will be 300m. The space between two consecutive troughs or crests is understood as the wavelength.
What is wavelength?The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.
The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.
The given data in the problem is;
v is the speed = 1500 m/s
f is the frequency= 5 Hz.
λ is the wavelength of the wave=?
The relationship between the wave's wavelength, frequency, and speed is given as
wavelength = speed of wave / frequency
The wavelength of the wave is found as;
[tex]\rm \lambda= \frac{v}{f} \\\\ \rm \lambda= \frac{1500}{5} \\\\ \rm \lambda=300 \ m[/tex]
Hence the wavelength of the wave will be 300m.

3. A bus is moving at 25 m/s when the driver steps on the brakes and brings the bus to a stop in 3.0 seconds. What is the average acceleration of the bus while braking?
Answers
Answer:
-8.3 m/s²
Explanation:
The acceleration of an object is defined as the change in velocity over the change in time.
a = Δv/Δt a = (v - v₀)/tWe are given the velocity of the bus, 25 m/s, and the time it takes the bus to stop, 3.0 s.
We know that if the bus stops, its velocity must be 0 m/s. Therefore, we can use these numbers to substitute into the acceleration formula.
a = (25 - 0)/3.0 a = 25/3 a = 8.33333333...The magnitude of the average acceleration of the bus while braking is 8.3 m/s².
However, in order for the bus to slow down and stop, the acceleration must have the opposite sign of the velocity.
This means that the acceleration is negative whilst the velocity is positive. So, the average acceleration of the bus while braking is -8.3 m/s².

Q2.What follow-up questions would be appropriate for the 15-year-old girl’s visit to the nutrition clinic, and why? What additional notes, if any, might be appropriate to enter into her electronic medical record, depending on her answers?
Q3.Based on everything you’ve read, which symptoms could indicate an eating disorder that might not be detectable by measuring BMI? What subjective and objective observations could you use to help detect other eating disorders in a clinical setting like the one described in this scenario?
Q4.Based on everything you’ve learned, explain which elements (symptoms, causes, contributing factors, etc.) of bulimia and/or anorexia are biological and physiological, and which are psychological, and which elements are sociological (based on an individual’s place in society, their relationship with other people, and the culture they live in). Include at least one element each for the physiological, psychological, and sociological elements.
Q5.Finally, engage in some independent research to examine BMI in more detail. Look up information that covers the following considerations:
- Limitations of the BMI scale, including considerations related to age, lifestyle, etc.
- How a BMI can be used as part of a “growth chart,” turning it from a one-time absolute measure of health into a dynamic measure of change over time
- How human’s nutrition needs change by age and lifestyle, e.g., do student athletes have different nutrition needs than average students? What about adult athletes?
Part Two i need one paragraph explaining this
The US Department of Agriculture has released an online tool, Choose My Plate, that aims to help people of all ages make healthy nutrition plans for themselves. Other countries have similar programs, so if you live outside the United States, you might see what your local recommendations are. Either way, remember these are just general guidelines, and ideally you would work directly with a physician or dietician to formulate a more individualized dietary plan.
Use the MyPlate Plan calculator on that site to find which calorie level is appropriate for you and follow its link to see your semi-personalized MyPlate plan. Based on the results, write a short paragraph explaining how closely you think your meals matched the proposed plan over the last three days. (If you want to make it even more relevant and you have the time, track everything you eat over the next three days and then write the paragraph. You might find that you get a more precise picture this way.) Are there areas for improvement, and if so, what steps might you take to achieve that improvement? Are there elements about your life that would make it difficult to keep to the proposed plan, like living in a food desert or not having healthy cafeteria options?

Providers must also remain alert for disordered eating in female athletes (the female athlete triad) and disordered eating in diabetics. Treatment requires a multidisciplinary team including a primary care practitioner, nutritionist, and mental health professional. The role of the primary care practitioner is to help determine the need for hospitalization and to manage medical complications (e.g., arrhythmias, refeeding syndrome, osteoporosis, and electrolyte abnormalities such as hypokalemia).

Resolving the applied force:
To solve this problem, we will first make a free-body diagram (attached)
The Applied force has been resolved into 2 components denoted by a thinner line and 'g' is the acceleration due to gravity
We found the values by using basic trigonometry
Finding the Normal Force:
Normal force is equal and opposite to the net force applied on the ground. So, we will subtract the vertical component of the applied force from the weight of the crate.
Normal force = mg - F*Sin(27°)
Normal force = [(71)*(9.8)] - [ (577)(0.454) ] [g = 9.8 m/s²]
Normal Force = 433.84 N

A voltage is applied to a resistor,
which creates a 1.50 A current. If
you double the resistance, keeping
the voltage the same, what will the
new current be?
(Unit = A)
Answers
Answer:
Explanation:
By Ohms Law, Voltage = Current * Resistance
Keeping the voltage the same and doubling the resistance, the current will be halved.
So the new current = 1.5/2 = 0.75A
By using Ohms law, the current will be 0.75A.
What is Ohm's law?Ohm's law states that the current flowing through a resistance is proportional to potential difference across the resistance under constant temperature and pressure conditions. Ohm's law can be expressed as:
V =IR
Here, I = 1.50 AR = R Ωso, V = 1.50 R Now Voltage is same but resistance is doubled so new resistance is
Now, put the values of given data in ohms law formula:
2RI = 1.50 R/ 2R = 0.75A
Hence current is 0.75A

You can use the curved part of a spoon as a mirror because it ________ light.
Which best completes the statement?
reflects
refracts
absorbs

Answers
Answer:
Reflects
Explanation:
A metal spoon looks very shiny because its surface is very smooth, which is why it acts like a mirror and reflects light very well.
You can use the curved part of the spoon as a mirror because it reflects light. Thus, the correct option is A.
What is reflection of light?Reflection is the phenomena of light, when the ray of light bounces off an object. If the surface is smooth and shiny, just like a glass, water or polished metal surface, the light will reflect at the same angle as it hit the surface of the object. This is called as specular reflection.
The laws of reflection states that the incident ray, the reflected ray, and the normal ray all lie at the same point of incidence, and lie in the same plane of the surface. And, the angle of incidence is equal to the angle of reflection of light.
Therefore, the correct option is A.
