A luge and its rider, with a total mass of 86 kg, emerge from a downhill track onto a horizontal straight track with an initial speed of 25 m/s. If a force slows them to a stop at a constant rate of 3.1 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 6.2 m/s2?
please show step by step when answering

A sled and rider (combined mass of 78 kg) finish a downhill run with a speed of 26 m/s, then enter a flat (horizontal) area where the sled slows down at a constant rate of -2.2 m/s2 until it stops. What distance did the sled move while slowing down? Your answer should be in m, but enter only the numerical part in the box.

A car of mass 500. kg on a roller coaster ride is raised from
the ground (horizontal dotted line) to point A as shown in the
diagram above. When the car passes point A, its speed is 5.0 m/s,
and then it rolls freely through the rest of the ride with
negligible friction, passing points B, C, D and E. Note that point
D is the highest portion of a circular loop, and point E is the
lowest portion of...
