2) After playing a game of pinball, you decide to do some calculations on the launching mechanism. The pinball and the plunger have a mass of 0.30 kg and 0.50 kg respectively. The spring coefficient in the pinball machine is 300 N/m. The original length of the spring is 100 mm and the compressed length is 35 mm. If the coefficient of friction between the ball and the surface is 0.15, calculate the velocity of the ball right before it loses contact with the plunger (in m/s). Note that the plunger is never in contact with the ground and assume the ball slides without rolling. [Ans. to check: 1.23 m/s]

spring coefficient in the pinball machine is 300 N/m. The original length of the spring is 100
mm and the compressed length is 35 mm. If the coefficient of friction between the ball and
the surface is 0.15, calculate the velocity of the ball right before it loses contact with the
plunger (in m/s). Note that the plunger is never in contact with the ground and assume the
ball slides without rolling. [Ans. to check: 1.23 m/s]
