A luge 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. If a force slows them to a stop at a constant rate of 2.0 m/s2,
(a) What magnitude F is required for the force,
(b) What distance d do they travel while slowing, and
(c) What work W is done on them by the force? What are?
(d) F,
(e) d, and
(f) W if they, instead, slow at 4.0 m/s2?
