3. Hooke's Law: A force of 12 N stretches a spring 10 cm. What force is required to stretch the spring
15 cm?

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.

This is the number of complete movements of a wave per second.

Properties seen when one one substance changes to another are known as properties
