Chapter 8, Problem 2(choose chapter or problem)
In Fig. 8-29, a single frictionless roller-coaster car of mass m 825 kg tops the first hill with speed v0 17.0 m/s at height h 42.0 m. How much work does the gravitational force do on the car from that point to (a) point A, (b) point B, and (c) point C? If the gravitational potential energy of the carEarth system is taken to be zero at C, what is its value when the car is at (d) B and (e) A? (f) If mass m were doubled, would the change in the gravitational potential energy of the system between points A and B increase, decrease, or remain the same? SS hillABCh hh/2v0Figure 8-29 2 and 9.
