a rock stuck in the tread of a 59cm diameter bicycle wheel has a tangential speed of 3.2m/s. When the brakes are applied, the rock's tangential deceleration is 1 m/s^2.
What is the magnitudes of the rock's angular velocity at t= 1.50s.
What is the magnitudes of the rock's angular acceleration at t= 1.50s ?
At what time is the magnitude of the rock's acceleration equal to g(gravity)
