A billiard ball of mass m = 0.250 kg hits the cushion of a billiard table at an angle of θ1 = 63.4° at a speed of v1 = 24.8 m/s. It bounces off at an angle of θ2 = 71.0° and a speed of v2 = 10.0 m/s.

(a) What is the magnitude of the change in momentum of the billiard ball?

1

(b) In which direction does the change of momentum vector point? (Let up be the +y positive direction and to the right be the +x positive direction.)

2° (counter-clockwise from the +x-axis)
