A ball is dropped vertically from a height d above the ground it hits the ground and bounces up vertically to a height d/2. Neglecting subsequent motion and air resistances, its velocity v varies with the height h above the ground as

A ball is dropped vertically from a height d above the ground. It hits the ground and bounces up vertically to a height d/2. Neglecting subsequent motion and air resistance, its velocity v varies with the heiht h above the ground as

A ball is dropped from a height h above ground. Neglect the air resistance, its velocity (v) varies with its height (y) above the ground as :-

A ball is thrown upwards with a speed u from a height h above the ground.The time taken by the ball to hit the ground is

A body is dropped from a height of 16 m. The body strikes the ground and losses 25% of its velocity. The body rebounds to a height of

A ball P is dropped vertically and another ball Q is thrown horizontally with the same velocities from the same height and at the same time. If air resistance is neglected, then

An object is dropped from a height h from the ground. Every time it hits the ground it looses 50% of its kinetic energy. The total distance covered as t to oo is -

A stone dropped from a cliff hits the ground in 4 sec. Height of the cliff is

A ball dropped from a height of 2 m rebounds to a height of 1.5 m after hitting the ground. Then fraction of energy lost is

A ball is dropped from a height of 19.6 m above the ground. It rebounds from the ground and raises itself up to the same height. Take the starting point as the origin and vertically downward as the positive X-axis. Draw approximate plots of x versus t, v versus t and a versus t. Neglect the small interval during which the ball was in contact with the ground.

A small metallic spherical ball is dropped from a height h . If it collides with the ground inelastically and rebounds, then
