A wire is 25.0 m long at 2 degrees celsius and is 1.19 cm longer at 30.0 C. Find the wires coefficient of linear expansion

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.
