Object 1 has a mass m1 and a velocity v? 1 = (2.40m/s )x^. object 2 has a mass m2 and a velocity v? 2= (3.30m/s )y^. the total momentum of these two objects has a magnitude of 19.0kg? m/s and points in a direction 70.0? above the positive x axis. find m1 and m2

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.

How do you tell if someone actually cares about you? and just say they do?
