KINEMATICS AND DYNAMICS OF CIRCULAR MOTION

Question

A 76-kg pilot at an airshow performs a loop de loop with his plane. At the bottom of the 52-m radius loop, the plane is moving at 48 m/s. Determine the net force acting upon the pilot.

Answer 1

Hey Edwin -

This probably mostly hinges on identifying that the net force for an object in circular motion is equal to the centripetal force. This will always be true for circular motion when the speed is not changing (which it never is in introductory courses).

So you can just say F_net = F_c = m*v²/R

From here it's just a matter of plugging in the given values, which I'll leave to you.
