Item 11 of 2Figure 1)A roller-coaster car may be represented by ablock of mass 50.0 kg. The car is released from rest at aheight h = 48.0 m above the ground and slides along africtionless track. The car encounters a loop of radius R =16.0 m at ground level, as shown. As you will learn in thecourse of this problem, the initial height 48.0 m is greatenough so that the car never loses contact with the track.Part AFind an expression for the kinetic energy K of the car at the top of the loop.Express the kinetic energy numerically, in joules.1] ?K =JFigure1 of 1SubmitRequest AnswerPart BFind the minimum initial height hmin at which the car can be released that still allows the car to stayin contact with the track at the top of the loop.Express your answer numerically, in meters.ΑΣφhmin =mP Pearson
