Conservation of Momentum in Two Dimensions
Classwork
A bowling ball with a momentum of 18 kg·m/s strikes a stationary bowling pin. After the collision, the ball has a momentum of 13 kg·m/s directed 55° to the left of its initial direction as shown below. What is the momentum (magnitude and direction) of the pin's resultant motion?
Before: 18 kg·m/s
After: 13 kg·m/s at 55°
