Question

a man throws a ball vertically upward with an initial speed of 20m/s . what is the maximum height reached by the ball and how long does it take to return to the point it was thrown.​

Answer 1

A ball is thrown vertically upward with a velocity of 20 m/s. calculate maximum height and time taken to reach maximum height. H = U2/ (2g) = (202)/ (2 x 9.8)=20.4 m T = U/g = 20/9.8 = 2.04 sec
