11.2 Boxes A and B are at rest on a conveyer belt that is initially at rest. The belt suddenly startsin an upward direction so that slipping instantly occurs between the belt and the boxes. Thekinetic friction coefficients between the belt and the boxes are μk,A = 0.3 and μk,B = 0.32.Determine the initial acceleration of each box. Will the blocks stay together, or separate?80 lb100 lbAB15°Hint: to see if the boxes stay together or separate, first assume they separate, and see if theirresulting motion (acceleration) validates that assumption. If the their motion is not consistentwith the assumption of separation, then they must stay together.

Step 1: Data Given mA = 100 lb, mB = 80 lb, μA=0.30 μB=0.32 Let us first draw the free body…

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] HO www
