A luge and its rider, with a total mass of 92 kg, emerge from a downhill track onto a horizontal straight track with an initial speed of 49 m/s. Assume that they stop with a constant deceleration of 3.2 m/s2. What magnitude F is required for the decelerating force? N What distance d do they travel while decelerating? m What work W is done on them by the decelerating force? kJ. What is F for a deceleration of 6.4 m/s2? N What is d for a deceleration of 6.4 m/s2? m What is W for a deceleration of 6.4 m/s2? kJ
