Question
In the figure below, a frictionless roller coaster of mass m = 511 kg tops the first hill with speed v0 = 4.7 m/s at height h = 53 m. How much work does its weight do on it from the initial point to point A? J How much work does its weight do on it from the initial point to point B? J How much work does its weight do on it from the initial point to point C? J The gravitational potential energy of the coaster-Earth system is taken to be zero at point C. What is its value when the coaster is at point 8? J What is its value when the coaster is at point A? JExplanation / Answer
b) mgh/2 = 132706.7 c) mgh = 265413.4 d)0 e)0
