Answer:
11.25 m/s^2
Step-by-step explanation:
m = 85 kg, v = 15 m/s, r = 20 m
When an object is moving around a circular path, it exerts a force towards the centre of the circular path which is called centripetal force and the acceleration produced is called centripetal acceleration.
The formula for the centripetal acceleration is given by
a = v^2 / r = 15 x 15 / 20 = 11.25 m/s^2
