Answer:
(A) Original velocity will be 7.244 m /sec
(B) Acceleration will be 
Explanation:
We have given distance covers by truck s = 40 m
Time taken by truck to cover this distance t = 7.45 sec
Final velocity v = 3.50 sec
According to second equation of motion
-----eqn 1
According to first equation of motion
v = u + at
So 
-----eqn2
Solving equation 1 and 2
a =
And u = 7.244 m /sec
(A) Original velocity will be 7.244 m /sec
(B) Acceleration will be
It conserves both energy and momentum in the collision at the same time. By design, when the balls collide the strings that hold them up are vertical (assuming balls are only swung from one side).
: Hope this helps :)
Answer:
M V R = constant angular momentum is constant because no forces act in the direction of V
Since M (mass) = constant
V R = constant
The force is directed along the gravitational force vector (towards the center of rotation)
The statement "<span>The motion of a pendulum for which the maximum displacement from equilibrium does not change is an example of simple harmonic motion." is true.
