A platform of infinite mass is moving upward with velocity `5 m//s`. At time `t = 0`, a ball which is at height `100 m` above the platform starts fallng freely. If the velocity of ball just after the collision is `10 v m//s` then value of v is (Assum elastic collision) `(g = 10 m//s^(2))`:

A platform of infinite mass is moving upward with velocity 5 m//s. At time t = 0, a ball which is at height 100 m above the platform starts falling freely. The velocity of ball just after the collision will be (Assume elastic collision) (g=10 m//s^(2)):

A ball is moving with velocity 2m//s towards a heavy wall moving towards the ball with speed 1m//s as shown in figure. Assuming collision to be elastic, find the velocity of ball immediately after the collision.

A ball of mass m moving with velocity V , makes a head on elastic collision with a ball of the same moving with velocity 2 V towards it. Taking direction of V as positive velocities of the two balls after collision are.

A ball of mass 10 kg is moving with a velocity of 10 m / s . It strikes another ball of mass 5 kg which is moving in the same direction with a velocity of 4 m / s . If the collision is elastic, their velocities after the collision will be, respectively

A ball of mass m_(1) is moving with velocity 3v. It collides head on elastically with a stationary ball of mass m_(2) . The velocity of both the balls become v after collision. Then the value of the ratio (m_(2))/( m_(1)) is

Two pendulum bobs of mass m and 2m collide elastically at the lowest point in their motion. If both the balls are releasd from height H above the lowest point, Velocity of the bob of mass m just after collision is
