Amover pushes a 30 kg crate across a level florr with a force of 250 n, but the crate accelerates at a rate of only 5.83 m/s squared because a friction force opposes the crate's motion. what is the magnitude of the force of friction?

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.
