Two vehicles A and B are moving in the opposite directions with the velocities of 20m/s and 25m/s respectively from the same place at the same time. Calculate the relative velocity of vehicle A with respect to vehicle B after 1 second.​

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.
