Question

A stunt rider is traveling clockwise around the inside of a vertical, circular loop of track, riding a motorbike at a constant speed of 16.1m/s.

a) Draw a FBD of the bike when its at the very top of the circular track and moving to the right. Neglect air resistance and friction

b) Although the bike's speed is constant, its acceleration isn't zero. Explain why, in 1~2 sentences without equations or calculations, starting with a brief definition of acceleration.

c) The magnitude of the bike's acceleration at this instant is 17.3m/s^2. Calculate the track's radius.

d) The normal force acting on the bike is 2648N. Use N2L to calculate the bike's mass.

e) Find the minimum speed necessary to keep the bike from falling off the track at this point.
