A ball is dropped from a height of a building while another is thrown horizontally at the same instant. Do they touch ground simultaneously?

Two stones are releassed from the same height. One is released from rest and the other is thrown horizontally. Which stone will touch the ground first ?

Statement I : A body is dropped from a height h and another body is thrown simultaneously from the ground with a velocity u in the vertically upward direction. The meet after a time of (h)/(u) . Statement II : For a body projected in the vertically upward direction the ascent in the last second is always 4.9 m, whatever be the velocity of projection.

A ball is dropped from a height of 1m onto a horizontal plane. The ball takes 1.3 s from its time of release for the second impact with the plane. Find the coefficient of restitution.

A ball is dropped from a height of 90m onto a horizontal plane rest. Find the total distance travelled by it before coming to rest. The coefficient of restitution e=0.5.

A ball A is dropped from a certain height h. Another ball B is thrown simultaneously from the ground vertically upwards with a velocity sqrt(gh) . When and where would the two balls cross each other?

When a certain golf-ball is dropped on a piece of pavement, it bounces to a height of three-fifth the height from which it fell. If the ball is dropped from a height of 100 cm, how far has it travelled when it hits the ground for the tenth time ? How high will it rise on the next bounce ?
