A billiard ball moving at 6.00 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 4.91 m/s, at an angle of 35.0° with respect to the original line of motion.(a) Find the velocity (magnitude and direction) of the second ball after collision.1.- … m/s2.- ° (with respect to the original line of motion, include the sign of your answer; consider the sign of the first ball’s angle)(b) Was the collision inelastic or elastic?
