What is the momentum of a 50kg carton that slides at 4m/s across an icy surface?

0 ⤊

And the sliding carton skids onto a rough surface and stops in 3s. Calculate the force of friction is encounters.

The momentum is mass times velocity.

Change in momentum = force multiplied by time. You know the change in momentum and the time; compute the force.

Momentum = velocity * mass
Acceleration = Chane in velocity / change in time.
