Homework Help: physics

Posted by Steph on Friday, November 26, 2010 at 5:02pm.

A rock stuck in the tread of a 57.0 cm diameter bicycle wheel has a tangential speed of 3.00 m/s. When the brakes are applied, the rock's tangential deceleration is 1.40 m/s^2.
A) What is the magnitudes of the rock's angular acceleration at t=1.60 s?
B) At what time is the magnitude of the rock's acceleration equal to g? (Remember that you need to include both tangential and radial accelerations in computing the magnitude of the rock's acceleration.)
