Question

A ball is thrown vertically upwards and rises to a height of 126.5 m. Calculate the

(1) velocity by which the ball was thrown upwards and


(2) the time taken by the ball to reach the highest point.
(Given is g​

Answer 1

Answer:

Here, u is the initial velocity v is final velocity and h is height at which ball reached. At height 126.5 m (maximum height) , the final velocity is zero. Thus, the velocity by which the ball was thrown is 49.79 m/s. t = 5.08 s.
