Question

two balls of different masses, one lighter and other heavier are thrown vertically upward with same initial speed. which one will rise to the greater height?

Answer 1

both of them will attain same maximum height as acceleration due to gravity is independent of mass. and both the bodies are projected with same initial speed

Answer 2

Explanation:

Wheb a ball is projected veritially upward with speed u, the maximum height attained, hmax=u2/2g, which is independent of mass of ball. Thus both the balls ( of different masses) will attain same height when projected vertically upward wigh the same velocity.
