In the braking test of a sports car, its velocity is reduced from 70 mi/h to zero in a distance of 180 ft with slipping impending. The coefficient of kinetic friction is 80 percent of the coefficient of static friction.(b) the stopping distance forteh same initial velocity if the car skids. Ignore airresistance and rolling resistance.

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping
