ok. lets see
1st law of motion
body at rest stays at rest, body moving with constant velocity will do so
So for bobsleding, they push the darn cars to make it move. Gravity takes affect when they get in so a constant force of gravity is always there. They minimaze drag and friction to keep it going. And they all learn to turn so that they do not slow down when exiting a turn.
2nd Law
The vector sum of all forces is equal to mass times acceleration (F = ma)
Well... let me see,
since the lil push cart (got that from cool runnings) keeps on moving, engineers, scientist try and figure a way so that the force of gravity is great as well as the initial force to move the vechile. They make it look like a bullet to minimize drag. They put on blades to cut through the ice and the participants all use that fancy shmancy clothing and helmet to minimize drag also
3rd law of motion
action-reaction pair
well, it sits on the ice. these pairs do not combine to give a net foce and do not cancel each other out and so you have a normal force and the weight of the object
hope this helps and i could be totally wrong

Friction will slow you down if the ice or snow is not packed down. I think I got it right.
