Noel is studying momentum at a bowling alley. He rolls a bowling ball down a lane to hit a bowling pin. The lane is smooth and polished to greatly reduce friction. Noel measures the velocity of the ball before and after it hits the pin. The ball is sliding before and after it hits the pin, it
carries the pin with it, as shown in the diagram.
Before
8 m/sec 0 m/sec
After
6.5m/sec
6.5 kg 1.5 kg

Noel claims that the bowling ball-and-pin system demonstrates conservation of momentum.

Which equation represents the interaction in the diagram?

A: (6.5 kg)(8 m/sec) + (1.5 kg (0 m/sec) = (6.5 kg)(6.5 m/sec) + (1.5 kg)(6.5 m/sec)

B: (8 m/sec (0 m/sec) = (6.5 m/sec)(0 m/sec)

c: (8 kgm/sec) - (15 kgm/sec) = (6.5 kgm/sec) + (0 kgm/sec)

D: (1.5 kg)(6.5 m/sec)=(1.5kg) (6.5 m/sec)
