Choose the correct statement(s).

If the greatest height to which a man can throw a stone is h, then the greatest horizontal distance upto which he can throw the stone is 2h.

The angle of projection for a projectile motion whose range R is n times the maximum height is tan-1(4/n).

The time of flight T and the horizontal range R of a projectile are connected by the equation gT2=2Rtan⁡θ, where θ is the angle of projection.

A ball is thrown vertically up. Another ball is thrown at an angle θ with the vertical. Both of them remain in air for the same period of time, then the ratio of heights attained by the two balls is 1 : 1.
