A ball is thrown horizontally from a cliff such that it strikes the ground after `5s`.The line of sight makes an angle `37^(@)` with the horizontal.The initial velocity of projection in `ms^(-1)` is

A object is thrown horizontally from a point A. The ball hits the ground at a point B. The line of sight from A to B makes 60° with the horizontal. If g = 10ms^(-2) , the velocity of projection, if the time of flight is sqrt(3) sec. is

A stone is thrown horizontally from the top of a cliff and strikes the ground after 5 seconds, at an angle of 45^(@) with the horizontal . Calculate (i) height of the cliff. (ii) speed of projection of the stone .

From the the top of a tower 19.6 m high, a ball is thrown horizontally. If the line joining the point of projection to the point where it hits the ground makes an angle of 45^(@) with the horizontal, then the initial velocity of the ball is:-
