A luge and its rider, with a total mass of 82 kg, emerge from a downhill track onto a horizontal straight track with an initial speed of 43 m/s. Assume that they stop with a constant deceleration of 3.2 m/s2.
(a) What magnitude F is required for the decelerating force?
(b) What distance d do they travel while decelerating?
(c) What work W is done on them by the decelerating force?
(d) What is F for a deceleration of 6.4 m/s2?
(e) What is d for a deceleration of 6.4 m/s2?
(f) What is W for a deceleration of 6.4 m/s2?
