A 150 g pinball rolls towards a springloaded launching rod with a velocity of 2.0 m/s

to the west. The launching rod strikes the pinball and causes it to move in the

opposite direction with a velocity of 10.0 m/s. What impulse was delivered to the

pinball by the launcher?

A 0.75 kg•m/s to the east

B 1.2 kg•m/s to the east

C 1.8 kg•m/s to the east

D 3.0 kg•m/s to the east
