Question

a ball is thrown vertically upwards with velocity of 20 m per second from the ground at t=0 second what is the velocity of the ball at t=2 second

Answer 1

Given:- u = 20 m / s; v = 0 m/s (because when it reaches the maximum height, then velocity is zero); g = 9.8 m / s 2. Formulae:- v = u − g t ...
