A car starts with constant acceleration `a=2m//s^(2)` at t=0. two coins are released from the car at t=3 and t=4 . Each coin takes 1 second to fall on ground. Then the distance between the two coins will be (Assume coin sticks to the ground)

A ball is released from the top of a tower of heighth metre. It takes T second to each the ground. What is the position of the ball at T/3 second ?

There are two cars on a straight road, marked as x axis. Car A is travelling at a constant speed of V_(A) = 9 m//s . Let the position of the Car A, at time t = 0 , be the origin. Another car B is L = 40 m ahead of car A at t = 0 and starts moving at a constant acceleration of a = 1 m//s^(2) (at t = 0). Consider the length of the two cars to be negligible and treat them as point objects. (a) Plot the position–time (x–t) graph for the two cars on the same graph. The two graphs intersect at two points. Draw conclusion from this. (b) Determine the maximum lead that car A can have.

A car starts from rest and moves with constant acceleration. In first t seconds it covers distance x. Then distance covered by it in next t seconds will be:-

An elevator car whose floor to ceiling distance is equal to 2.7 m starts ascendiung with constant acceleration 1.2(m)/(s^(2)) , 2 sec after the start a bolt begins falling from the ceiling of the car. Answer the following question g=9.8 m//s^(2) Distance covered by the bolt during the free fall time w.r.t. ground frame.

A disc starts rotating with a constant angular acceleration of 1 rad//s^(2) about a fixed vertical axis perpendicular to its plane and passing through its centre. A coin of mass 10 gm is placed on the disc at a distance of 10cm from the axis. The coefficent of friction between the disc and the coin is 0.2 . The value of the frictional force on the coin at t=1s will be

A car starts from rest and accelerates at 5 m/s^2 . At t = 4s, a ball is dropped out of a windown by a person sitting in the car. What is the velocity and acceleration of the ball at t = 6s?

A car starts from rest moves with uniform acceleration a_(1) for t_(1) second and then retards uniformly at a rate a_(2) for t_(2) second. Then t_(1)//t_(2) is equal to
