Five balls are placed one after the other along a straight line as shown in the figure. Initially, all the balls are at rest. Then the second ball has been projected with speed `v_(0)` towards the third ball. Mark the correct statements, (Assume all collisions to be head-on and elastic.)

The speed time graph of a ball of mass 30g moving along a straight line is shown in (figure). Calculate the opposing force that brings the ball to rest.

A ball A of mass M collides elastically with a similar ball B at rest as shown in figure. Initially velocity of ball A is u m/s. After collision,

A ball A of mass M collides elastically with a similar ball B at rest as shown in figure. Initially velocity of ball A is u m/s. After collision,

Two balls of masses 2 m and m are moving with speed 2 v_(0) and v_(0) towards each other. If the coefficient of restitution e = 1//3 , the speed of balls , if collision is head - on

Three identical balls, ball I, ball II and ball III are placed on a smooth floor on a straight line at the separation of 10m between balls as shown in figure. Initially balls are stationary. But I is given velocity of 10m//s towards ball II, collision between balls I and II is inelastic with coefficient of restitution 0.5 but collision between balls II and III is perfectly elastic. What is the time interval between two consecutive collisions between ball I and II?
