Question

1. Danielle throws a ball vertically upwards with an initial velocity of 24.5 ms-1, and catches it at the same height. a) Calculate the time taken for the ball to reach its maximum height?

Answer 1

2.50 s

Step-by-step explanation:

At the maximum height, the velocity is 0.

Given:

u = 24.5 m/s

v = 0 m/s

a = -9.8 m/s²

Find: t

v = at + u

0 = (-9.8) t + 24.5

t = 2.50 s
