A car is accelerating from rest. There is a 1.6 g pebble stuck in the tread of one of the tires 0.38 m from the center of rotation. The pebble is held in place with static friction which has a maximum value of 3.6 N. What speed does the car reach when the pebble pulls out of the tread? Use Newton's 2nd Law and centripetal acceleration to solve this. Think about the relationship between the translational speed of the car and the tangent speed of the pebble.
