A light spring of length l and rigidity k is placed vertically on a table. A small ball of mass m falls on it. Determine the height h from the surface of the tube at which the ball will have the maximum velocity.

A massless spring of length l and spring constant k is placed vertically on a table. A ball of mass m is just kept on top of the spring. The maximum velocity of the ball is

A massless spring of length l and spring constant k is placed vertically on a table. A ball of mass m is just kept on top of the spring. The maximum velocity of the ball is

A ball of mass m is attached to a light string of length L and suspended vertically. A constant horizontal force, whose magnitude F equals the weight of the ball, is applied Determine the speed of the ball as it reaches the 90^(@) level.
