A billiard ball of mass m = 0.15 kg strikes the cushion of a billiard table at θ1 = 48° and a speed v1 = 27 m/?

A billiard ball of mass m = 0.15 kg strikes the cushion of a billiard table at θ1 = 48° and a speed v1 = 27 m/s. It bounces off at an angle of θ2 = 71° and a velocity of v2 = 15 m/s. What is the magnitude of its change in momentum (in kg·m/s)?
