Problem # p037

Work - Energy Method
A roller coaster ( weight equals 1000 lbf ) moves along on a track having a velocity of 50 ft/sec at point A and heading towards point B.
Assume that the energy loss due to rolling friction and drag between points A and B equals 10,000 ft lbf.
Determine the maximum height "h" of the rise from point A to point B that the coaster can just clear under these circumstances.
