Question

A car (1000 kg) is going 20 m/s on a level road and slams on the brakes. The skid marks are 25m long.

If the force of friction is constant over the 25m skid, what is the magnitude of the force?

Definition Definition Force that opposes motion when the surface of one item rubs against the surface of another. The unit of force of friction is same as the unit of force.
