Chapter 6, Problem 6.46(choose chapter or problem)
In Example 10, we ignored nonconservative forces, such as friction. In reality, however, such forces are present when the roller coaster descends. The actual speed of the riders at the bottom is 45.0 m/s, which is less than that determined in Example 10. Assuming again that the coaster has a speed of 6.0 m/s at the top, find the work done by nonconservative forces on a 55.0-kg rider during the descent from a height h0 to a height hf, where h0 hf 127 m.
