A 10 kg box is pushed from rest by a truck for 2m. Once the truck stops pushing the box it is traveling 6 m/s.This box slides for 5 seconds before coming to a stop. If the specific heat is 2 joules per degree kg, how much did the temperature of the box change by and what is the average force applied by the truck?

    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!!
