A luge and its rider, with a total mass of 86 kg, emerge from adownhill track onto a horizontal straight track with an initialspeed of 40 m/s. Assume that they stop with a constant decelerationof 2.3 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 4.6 m/s2?

(e) What is d for a deceleration of 4.6 m/s2?

(f) What is W for a deceleration of 4.6 m/s2?

I have the answers that are looking for distance correct, but Ican't seem to get W or F
