During a 7.0 second interval, an object’s velocity changes from 74 m/s East to 32 m/s East. What is the magnitude and direction of the object’s acceleration?

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.
