A luge (sled) and its rider, with a total mass of 85 kg, emerge from a downhill track onto a horizontal straight track with an initial speed of 37 m/s, and they stop after undergoing a constant deceleration of 2.0 m/s^2.
a. What magnitude force is required to cause this deceleration?
b. What distance do they travel while decelerating?
c. What work is done on them by the decelerating force?
d. What are the answers to a, b and c for a deceleration of 4.0 m/s^2.
