Bah,I'm soconfused. This is not clearly stated in my textbook (because it'sconceptual.)Is itpossible for the rigid object to be in rotational motion about afixed axis if the net torque equals zero?
Abilliard ball moving at 5.80m/s strikes a stationary ball of the same mass. After thecollision, the first ball moves at5.30 m/s at an angle of 24.0°with respect to the original line of motion. Assuming an elasticcollision (and ignoring friction and rotational motion), find thestruck ball's velocity after the collision.
