Statement -1 : Two projectiles are launched from the top of a cliff with same initial speed with different angles of projection. They reach the ground with the same speed. Statement -2 : The work done by gravity is same in both the case

A projectile is fired from the top of an 80 m high cliff with an initial speed of 30(m)//(s) at an unknown angle. The speed when its hits the ground.

Two projectiles are fired from the same point with the same speed at angles of projection 60^(@) and 30^(@) respectively. Which one of the following is true?

Statement-1: Two stones were projected simultaneously from same point with same speed at different angles from horizontal as shown. They may collide at the point of intersection of their paths. Statement-2: For two particles to collide they must be at the same point in space simultaneously.

Two particles are thrown with same initial speed from the same point with angles of projection 42^0 and 48^0 . Find relation between ranges and heights.
