I know exactly where you get this question from :) It says rides up a slope, so that means that the distance of the hypotenuse is the slope, which is 1200m. So just find the loss of kinetic energy in the ride, which is equal to the work. He has to overcome of the loss of kinetic energy to...

thank you! especially that last bit about the chain, never knew that! :biggrin:

Homework Statement A carnival ride has a large horizontal steel disc of radius 5.0 m from which cars are suspended by 6.0 m long chains. The disc is rotated about its axis so that the cars swing out and revolve in a circular path. At its operating speed, the angle of the chains to the...
