a train moving at a speed of 15 m/s is accelerated to 45 m/s over a 12 s period. what is the acceleration?
Answer:
2.5 m/s²
Explanation:
Given:
v₀ = 15 m/s
v = 45 m/s
t = 12 s
Find: a
a = (v − v₀) / t
a = (45 m/s − 15 m/s) / 12 s
a = 2.5 m/s²

A 660 kg car is travelling around a circular track of radius 55.0 m at 11.5 m/s.
Calculate the force and its direction that provides the centripetal force acting on the car to keep it
in the circular path. (3 points)
a) 24 N toward the center of the circle
b) 24 N along the line tangent to the circle
c) 1.587 E3 N along the line tangent to the circle
d) 1.587 E3 N toward the center of the circle
Answer: D) 1.587 E3 N toward the center of the circle
This is the same as saying 1.587*10^3 newtons, or we can say 1587 newtons
=================================================
Work Shown:
m = mass = 660 kilograms
v = velocity = 11.5 meters per second
r = radius of circle = 55.0 meters
-------------
F = centripetal force = inward pulling force toward center of circle
F = (m*v^2)/r
F = (660*11.5^2)/55
F = 1587
F = 1.587 * 10^3
F = 1.587 E 3
The "E 3" notation is what many calculators display scientific notation to be
The units for the force here are in newtons.
The force is pulling on the object toward the center of the circle, which helps keep the car on the circular path, rather than it going off on a tangent.
A ball thrown vertically upward reaches a maximum height of 30 meters above the surface of Earth. At its maximum height, the speed of the ball is
Answer:
0 m/s
Explanation:
In this problem,
A ball thrown vertically upward reaches a maximum height of 30 meters above the surface of Earth. We need to find the speed of the ball at the maximum height. When an object reaches its maximum height, after then it starts to decrease its speed. As a result, the speed of the ball will be equal to 0 m/s.
The speed of the ball thrown upwards is zero when the object reaches maximum height.
The given parameter:
maximum height, h = 30 mThe velocity of an object thrown upwards decreases with time because the object is moving against gravity, and the eventually becomes zero when the object reaches maximum height.
[tex]v_f = v_0 - gt= 0[/tex]
Thus, the speed of the ball thrown upwards is zero when the object reaches maximum height.

Gamma rays are given out by the nucleus of certain radioactive materials. Radioactive material ray causes harm to the human beings and environment.
What is gamma-decay?Gamma decay is the production of extremely high-frequency electromagnetic radiation in order to stabilize the unstable nucleus. You must be well-versed in the various energy levels found in an atom.
The Nucleus has its own amount of energy. Gamma decay is the nucleus' method of transitioning from a higher energy level to a lower energy level by emitting high energy photons.

The whale shark is the largest of all fish and can have the mass of three adult
elephants. Suppose that a crane is lifting a whale shark into a tank for delivery
to an aquarium. The crane must exert an unbalanced force of 2.5 x 104 N to
lift the shark from rest. If the shark's acceleration while being lifted equals
1.25 m/s², what is the shark's mass?
Answer:
m = 20,000 kg
Explanation:
Force, [tex]F=2.5\times 10^4\ N[/tex]
Acceleration of the shark, [tex]a=1.25\ m/s^2[/tex]
It is required to find the mass of the shark. Let m is the mass. Using second law of motion to find it as follows :
F = ma
Putting the value of F and a to find m
[tex]m=\dfrac{F}{a}\\\\m=\dfrac{2.5\times 10^4}{1.25}\\\\m=20,000\ kg[/tex]
So, the shark's mass is 20,000 kg.
An object of mass(0.8kg) is attached to massless string of length (2.0),and swung with a tangential velocity of (3.0m/s) what is the tension in the string?
Answer:
3.6 N
Explanation:
The magnitude of centripetal force in this case is equal to the magnitude of tension in the spring.
The formula is :
T= mv²/r ------where T is tension
m= mass of object =0.8 kg
v= velocity of object {tangential velocity} = 3.0 m/s
r= length of string = 2m
Applying the formula with real values;
T= mv²/r
T= {0.8 * 3²} / 2
T= { 7.2}/2 = 3.6 N

An object travels in a straight line for 1200 m at a velocity of 50 m/s, what is its time of travel?
Given that,
distance = d = 1200m
velocity/speed = s = 50m/s
time = t
Also,
s = d/t
And,
t = d/s
t = 1200/50
t = 120/5
t = 24
Therefore, it takes 24s to travel.
Answer: Therefore, the travel time of a car that travels 1200 meters at 50 m/s is 24 seconds.
Explanation:
An object travels in a straight line for 1200 m at a velocity of 50 m/s, what is its time of travel?
Data:
d = 1200 m
V = 50 m/s
t = ?
The formula for uniform motion is:
V = d/tWhere
V = speedd = distancet = timeWe clear the formula for time t:
t = d/v
t = (1200 m)/(50 m/s)
t = 24 s
Therefore, the travel time of a car that travels 1200 meters at 50 m/s is 24 seconds.
A force of 25 newtons moves a box a distance of 4 meters in 5 seconds.
The work done on the box is [___] Nm, and the power is [___] Nm/s.
h e l p
Answer:
100 Nm and 25Nm/s.
Explanation:
Given the following data;
Force = 25N
Distance = 4m
Time = 5secs
To find the workdone;
Workdone = force * distance
Substituting into the equation, we have;
Workdone = 25*4
Workdone = 100 Nm
To find the power consumed;
Power = workdone/time
Substituting into the equation, we have;
Power = 100/4
Power = 25Nm/s
The work done on the box is 100 Nm, and the power is 25 Nm/s.
