A billiard ball of mass m= 0.150 kg hits the cushion of a billiard table at an angle of θ1= 44.0° at a speed of v1= 2.60 m/s. It bounces off at an angle of θ2= 49.0° and a speed of v2= 2.20 m/s. What is the magnitude of the change in momentum of the billiard ball? In which direction does the change of momentum vector point? (Take the x-axis along the cushion and specify your answer in degrees.)
