Question

A 50.0 kg child takes a ride on a Ferris wheel that rotates with a tangential speed of 1.2 m/s. Find the centripetal force that maintains the circular motion of the child if the distance from the center of the Ferris wheel is 16.0 m.

Answer 1

Centripetal force is F=mv^2/r. So F=50(1.2^2)/16=4.5J

Answer 2

4.5 N

Step-by-step explanation:

When an object is in circular motion, it experiences a force towards the centre of circular path. This force is called centripetal force. The value of centripetal force is given by

F = mv^2/r

F = 50 × 1.2 ×1.2 / 16

F = 4.5 N
