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.

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
