JEE Main Physics question

From the top of a tower, a body is projected vertically up, another body is horizontally thrown, and a third body is thrown vertically down, all with the same speed. Then

(A) strikes the ground with more velocity
(B) strikes the ground with less velocity
(C), , strike the ground with the same velocityCorrect
(D) and strike the ground with more velocity than

Answer: (C)

Solution

By energy conservation, each body has the same initial kinetic energy (equal speed) and falls through the same height, so each gains the
