A luge and its rider, with a total mass of 85.0 kg, emerge from a downhill track onto a horizontal straight track with an initial speed of 34.0 m/s. If a force slows them to a stop at a constant rate of 3.60 m/s, (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 7.20 m/s? (a) Number i Units (b) Number i Units (c) Number i Units (d) Number i Units (e) Number i Units (f) Number i Units
