Aforce of 240.0 n causes an object to accelerate at 3.2 m/s2. what is the mass of the object?

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.

What are similarities and differences between refraction, reflection, diffraction and absorption?
