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 5.39 m/s, at an angle of 26.0 with respect to the original line of motion

(a) Find the velocity (magnitude and direction) of the second ball after collision

  • physics - ,

    initial x momentum = 6 m
    initial y momentum = 0

    final x momentum = m(5.39 cos 26) + m Vx
    final y momentum = m (5.39 sin 26)+ m Vy
    m cancels
    initial = final
    solve for Vx and Vy
