A 4 kg box is pushed 2 m across a level surface by an applied force of 32 N, 0 degree. The box then slides an additional 3 m before coming to a rest.

a) Determine the amount of friction.

b) Determine the box's maximum speed over the 5 m distance travelled.

P.S. I have the answer, but I would really appreciate an explanation as to how to get the answer. Thank you!!
