In the figure shown, the heacvy ball of mass 2m rests on the horizontal surface and the lighter balls of mass m is dropped from a height `hgt2l.` At the instant the string gets taut, the upward velocity of the heavy ball will be :

In the shown figure, the heavu block of mass 2 kg rests on the horizontal surface and the lighter block of mass 1 kg is dropped from a height of 0.9 m . At the instant the string gets taut, find the upwards speed (in m//s ) of the heavy block.

In the shown figure, the heavu block of mass 2 kg rests on the horizontal surface and the lighter block of mass 1 kg is dropped from a height of 0.9 m . At the instant the string gets taut, find the upwards speed (in m//s ) of the heavy block.

In the shown figure, the heavu block of mass 2 kg rests on the horizontal surface and the lighter block of mass 1 kg is dropped from a height of 0.9 m . At the instant the string gets taut, find the upwards speed (in m//s ) of the heavy block.

A ball of mass m_(1) and another ball of mass m_(2) are dropped from equal height. If the time taken by the balls are t_(1) and t_(2) , respectively, then

A ball of mass m_(1) , collides elastically and head on with ball of mass m_(2) at rest. Then

In the figure, a ball of mass m is tied with two strings of equal as shown. If the rod is rotated with angular velocity omega_(1) when
