3) In a car crash against a wall, the front of the car crumples 1 meter. The car is going at an initial velocity of 40 m/s before the crash. a) What is the acceleration the car experiences?
b) How long does the crash take from beginning to end?

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.
