Question

A ball is thrown vertically upward with a speed of 25 /. How long does it take the ball to
reach its highest point?

Answer 1

Answer:

2.5 seconds

Explanation:

v = u + at

0 = 25 + (-10)t

10t = 25

t = 2.5

Answer 2

Explanation:

V = 25 m/s

Highest point = u²/2g

Highest point = (25)²/20 = 625/20=31.25 m
