A body is projected horizontally with a velocity `sqrt29` m/s from a height 10 m, the velocity on reaching the ground ………. m/s.

A ball of mass 2 kg is projected horizontally with a velocity 20m/s from a building of height 15m. The speed with which body hits the ground is :

A ball is projected horizontally with a velocity of 5 ms^(-1) from the top of a tower of height 10 m. When it reaches the ground (g=10 ms^(-2) )

A ball is projected vertically down with a velocity of 10sqrt(3) m//s from a height of 20 m. On hitting the ground if it loses 40 % of its energy, the height to which it bounces is (g = 10 ms^(-2))

The ball is projected vertically down with a velocity of 10sqrt(3)m/s from a height of 20m .On the hitting the ground if it loses 40% of its energy the height to which it bounces is (g=10ms^(-2))

A body is thrown horizontally with a velocity of v m/s from the top of a tower of height 2h reaches the ground in 't' seconds. If another body double the mass is thrown horizontally with a velocity 5v m/s from the top of another tower of height 8h it reaches the ground in a time of
