CHP H Loop the Loop Loop the Loop (Figure 1) A roller-coaster car may be represented by a block of mass 50.0 kg. The car is released to rest at a height = 48.0 m above the ground and slides along a frictionless track. The car encounters a loop of radius R - 16.0 m at ground level, as shown As you will learn in the course of this problem, the initial height 48.0 mis great enough so that the car never loses contact with the track Figure 1 of 1 Part A Find the kinetic energy K of the car at the top of the loop Express your answer numerically, in joules. 4 K- 24,000 B ?
