a 4kg block slides across a level floor at 1.7m/s and comes to a stop due to the friction present.

1) draw a pictrure and label all the forces on the box as it slides to a stop on the ground.

2) if the coefficient of friction between the two surfaces is 0.634. what is the magnitude of the force of friction?

3) what is the acceleration of the box?

4) if the box slides 0.24m, how much work does friction do? Include the sign
