Motion in a Circle
A particle P travels with constant speed in a circle of radius 5.6 m and completes one revolution in 36.0 s. The particle passes through O at t = 0 s.

What is the magnitude of the average velocity during the interval from t = 3.6 s and t = 12.5 s.

What is the magnitude of the instantaneous velocity at t = 3.6 s?

What is the magnitude of the instantaneous acceleration at t = 12.5 s?
