A white ball of mass 0.5 kg moving at 10 m/s collides with a 0.4 kg red pool ball initially at rest. After the collision, the white pool ball continues in the same direction with the velocity of 1.1 m/s. Neglacting friction, the velocity of the red ball after the collision is _ m/s

An electric current in a wire will push or pull on a permanent magnet. which statement best explains how an electric current creates an electromagnetic force on another magnet?

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.
