Explanation:
Una maquina lleva un paquete de 14 kg desde una posicion inicial de di = (1.5i + 1.75j + 1.2k) m en t = 0 a una posicion final df = (8.5i + 13j + 8.2k) m en t = 12 s. La fuerza constante que la maquina ejerce sobre el paquete es F = (2i + 4j + 6k) N. Para ese desplazamiento, encuentre (a) el trabajo que realiza la fuerza de la maquina sobre el paquete y (b) la potencia promedio de la fuerza de la maquina sobre el paquete
(a) Calculate the displacement r :
r = (8.5 i + 13 j + 8.2 k) m - (1.5 i + 1.75 j + 1.2 k) m
r = (7 i + 11.25 j + 7 k) m
The work W done by F in the direction of this displacement is
W = F • r = (2 i + 4 j + 6 k) N • (7 i + 11.25 j + 7 k) m
W = (2×7 + 4×11.25 + 6×7) Nm = 101 J
(b) The average power P of the machine is then
P = W / ∆t = (101 J) / (12 s)
P = 101/12 J/s ≈ 8.42 W
An ideal spring is mounted horizontally, with its left end fixed. The force constant of the spring is 170 N/m. A glider of mass 1.2 kg is attached to the free end of the spring. The glider is pulled toward the right along a frictionless air track, and then released. Now the glider is moving in simple harmonic motion with amplitude 0.045 m. The motion is horizontal (one-dimensional). Suddenly, Slimer* holding an apple flies in and approaches the glider. Slimer drops the apple vertically onto the glider from a very small height. The apple sticks to the glider. The mass of the apple is 0.48 kg.
Required:
Calculate the new amplitude of the motion of the glider with apple if the apple is dropped at the moment when the glider passes through its equilibrium position, x = 0 m.
Answer:
Explanation:
First of all we shall find the velocity at equilibrium point of mass 1.2 kg .
It will be ω A , where ω is angular frequency and A is amplitude .
ω = √ ( k / m )
= √ (170 / 1.2 )
= 11.90 rad /s
amplitude A = .045 m
velocity at middle point ( maximum velocity ) = 11.9 x .045 m /s
= .5355 m /s
At middle point , no force acts so we can apply law of conservation of momentum
m₁ v₁ = ( m₁ + m₂ ) v
1.2 x .5355 = ( 1.2 + .48 ) x v
v = .3825 m /s
= 38.25 cm /s
Let new amplitude be A₁ .
1/2 m v² = 1/2 k A₁²
( 1.2 + .48 ) x v² = 170 x A₁²
( 1.2 + .48 ) x .3825² = 170 x A₁²
A₁ = .0379 m
New amplitude is .0379 m

What is velocity ?
The directional speed of an item in motion, as measured by a specific unit of time and viewed from a certain point of reference, is what is referred to as velocity.
Velocity is the pace and direction of an item's movement, whereas speed is the time rate at which an object is travelling along a route. In other words, velocity is a vector, whereas speed is a scalar number.
Velocity is a unit of measurement for motion that begins in one location and moves to another. There are several practical uses for velocity, but one of the more frequent ones is figuring out how quickly you or anything in motion will go from one place to another.

C.
900 V.
D.

Answer:
AAAAAAAAaaaaaaaaaaaaaaaaaaaaaaaaaaaa
The voltage across the third resistor is 320 V.Therefore, the correct option is B.
What is voltage?When charged electrons (current) are forced through a conducting loop by the pressure of an electrical circuit's power source, they may perform tasks like lighting a lamp.
To find the voltage across the third resistor, we can use the voltage divider formula:
V₃ = (R₃ / (R₁ + R₂ + R₃)) x Vsource
where R₁, R₂, and R₃ are the values of the three resistors in series, and Vsource is the voltage of the source.
Putting in the given values, we get:
V₃ = (R₃ / (R₁ + R₂ + R₃)) x Vsource
V₃ = (R₃ / (300 + 280 + R₃)) x 900
We are not given the value of R₃, so we cannot directly calculate V₃. However, we can use the fact that the sum of the voltages across the three resistors must equal the voltage of the source:
V₁ + V₂ + V₃ = Vsource
Putting in the given values and simplifying, we get:
300 + 280 + V₃ = 900
V₃ = 320
Therefore, the voltage accross the third resistor is 320 V.Therefore, the correct option is B.

Your friend, who is in a field 100 meters away from you, kicks a ball towards you with an initial velocity of 16 m/s. Assuming the grass causes the ball to decelerate at a constant rate of 1.0 m/s2, how long does it take for the ball to reach you?
Answer:
Time, t = 5.355 seconds
Explanation:
Given the following data;
Distance = 100 m
Initial velocity = 16 m/s
Deceleration = 1 m/s²
To find the time, we would use the second equation of motion;
But since the ball is decelerating, it's acceleration would be negative.
S = ut + ½at²
Where;
S represents the displacement or height measured in meters.
u represents the initial velocity measured in meters per seconds.
t represents the time measured in seconds.
a represents acceleration measured in meters per seconds square.
Substituting into the equation, we have;
100 = 16t - 0.5t²
200 = 32t - t²
t² + 32t - 200 = 0
Solving the quadratic equation using the quadratic formula;
The quadratic equation formula is;
[tex] x = \frac {-b \; \pm \sqrt {b^{2} - 4ac}}{2a} [/tex]
Substituting into the equation, we have;
[tex] x = \frac {-32 \; \pm \sqrt {32^{2} - 4*1*(-200)}}{2*1} [/tex]
[tex] x = \frac {-32\pm \sqrt {1024 - (-800)}}{2} [/tex]
[tex] x = \frac {-32 \pm \sqrt {1024 + 800}}{2} [/tex]
[tex] x = \frac {-32 \pm \sqrt {1824}}{2} [/tex]
[tex] x = \frac {-32 \pm 42.71}{2} [/tex]
[tex] x_{1} = \frac {-32 + 42.71}{2} [/tex]
[tex] x_{1} = \frac {10.71}{2} [/tex]
x1 = 5.355
We do not need the negative value of x, so we proceed.
Therefore, time = 5.355 seconds

Two blocks are connected by a massless rope. The rope passes over an ideal (frictionless and massless) pulley such that one block with mass m1=14.25 kg is on a horizontal table and the other block with mass m2=7.5 kg hangs vertically. Both blocks experience gravity and the tension force, T. Find the magnitude of the tension in the rope, T, in newtons.
The magnitude of the tension in the rope of this two-block system is:
[tex]T=73.56\: N[/tex]
We have here an equilibrium system, which means that all forces acting are equal to zero.
We can analyze the hanging block. We just two forces acting in this block, the tension upwards (T) direction and the weight downward (W) direction.

Two ship fog horns have different frequencies. They are both being blown at the same time. You hear a sound that varies in amplitude, with the time between a minimum in loudness and the next maximum in loudness being 0.14 seconds. You know the fog horn with the lower pitch has a frequency of 173.5 Hz. What is the frequency of the fog horn with a higher pitch
Answer:
the frequency of the fog horn with a higher pitch is 177.07 Hz
Explanation:
Given the data in the question;
time between a minimum and the next maximum in loudness = 0.14 seconds
So,
Time T between the two continuous maximum in loudness will be;
⇒ T = 2 × 0.14 sec
T = 0.28 seconds
Thus, beat frequency [tex]f_b[/tex] will be;
[tex]f_b[/tex] = 1 / T
we substitute in the value of T
[tex]f_b[/tex] = 1 / 0.28
[tex]f_b[/tex] = 3.5714 Hz
Now, we know that; [tex]f_b[/tex] = [tex]f_2[/tex] - [tex]f_1[/tex]
we solve for [tex]f_2[/tex]
[tex]f_2[/tex] = [tex]f_b[/tex] + [tex]f_1[/tex]
given that; the lower pitch has a frequency of 173.5 Hz
we substitute
[tex]f_2[/tex] = 3.5714 Hz + 173.5 Hz
[tex]f_2[/tex] = 177.07 Hz
Therefore, the frequency of the fog horn with a higher pitch is 177.07 Hz

Assume that the roller coaster track has no friction, which means there's no heat transfer from
the track to the surroundings. How does lack of friction affect the energy of the roller coaster
System?
Answer:
No energy leaves the system if there’s no friction between the cars and the tracks.
Explanation:
The lack of friction affects the energy of the roller coaster system. Because no energy leaves the system if there is no friction between the cars and the rails.
What is the friction force?It is a type of opposition force acting on the surface of the body that tries to oppose the motion of the body. its unit is Newton (N).
Gravitational potential and kinetic energy, which are the roller coaster's usable energies, are converted to heat energy by friction.
A roller coaster is affected by air friction and resistance since it is in the air, and this creates a force that opposes the movement of the cart.
A portion of the energy is lost as a result of friction caused by the brakes, wind drag on the train, and friction between the wheels and the rails.
Since there is no friction on the roller coaster track, there is no heat transmission from the track to the environment.
The roller coaster system's energy is impacted by the absence of friction. Because if there is no friction between the automobiles and the rails, no energy exits the system.
Hence, lack of friction affects the energy of the roller coaster system.
