Let us throw a body with different velocities. Due to its low-velocity body describes a parabolic path and hits the earth surface at A. Similarly, on increasing velocity body hits the surface at B and makes a large horizontal range . Again on increasing the velocity body hits at C. At a certain velocity, the
