Question

A luge and its rider, with a total mass of 72.0 kg, emerge from a downhill track onto a horizontal straight track with an initial speed of 29.0 m/s. If a force slows them to a stop at a constant rate of 2.40 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 4.80 m/s2?

 

I know (a) is 172.8, and (d) is 345.6. I just need help with the rest.
