Two identical balls, of equal masses `A` and `B`, are lying on a smooth surface as shown in Fig. Ball `A` hits ball `B` (which is at rest) with a velocity `v = 16 m//s`. What should be the minimum value of coefficient of restitution between `A` and `B` so that `B` just reaches the highest point of inclined plane?

Two identical balls of equal masses A and B , are lying on a smooth surface as shown in figure Ball A hits the ball B (which is at rest) with a velocity v=16 m//s What should be the minimum value of coefficient of restitution e beteeen A and B so that B just reaches the highest point of inclined plane: ("Take" g=10 m//s^(2))

Two identical balls of equal masses A and B, are lying on a smooth surface as shown in the figure. Ball A hits the ball B (which is at rest) with a velocity v=16ms^-1 . What should be the minimum value of coefficient of restitution e between A and B so that B just reaches the highest point of inclined plane? (g=10ms^-2)

Two identical balls A and B lie on a smooth horizontal surface, which gradually merges into a curve to a height 3.2 m . Ball A is given a velocity of 10 m//s , to collide head-on with ball B , which then takes up the curved path. What is the minimum coefficient of restitution, e , for the collision between A and B in order that ball B reaches the highest point C of the curve.

Two identical balls A and B are moving as shown in the fig. Ball A hits a smooth floor head on with a velocity u and at the same instant ball B strikes A head on with a horizontal velocity u. The collision between A and B is perfectly inelastic whereas the coefficient of restitution for collision between A and the floor is e = 0.5 . At what time the two balls will collide again? Assume friction to be absent everywhere.

A ball A moving with a certain velocity collides, with another ball B of the same mass at rest. If the coefficient of restitution is e, the ratio of the velocities of A and B just after the collision is

A ball of mass moving with a velocity u collides head on with a ball B of mass m at rest. If the coefficient of restitution is e. the ratio of final velocity of B to the initial velocity of A is
