Consider the portion of a roller-coaster track shown below: 19.5 m B The height of the drop from point A to point B is h = 19.5 m, the velocity of the car and passengers at point A is vA = 6.25m/s and the mass of the car and passengers is m = 2350kg. (a) Assuming that friction is negligible, determine the speed of the car and passengers at point B. (b) If the actual friction forces cause the car and passengers to have a speed of vy = 18.9m/s at point B, how much work can be attributed to the friction forces? Remember, friction is a nonconservative force and the work done by friction is negative.
