Question
Because dissipative work, which is negative, converts mechanical energy into a thermal energy, Q, if we write Wats= Q, the above equation becomes %3D (KE + PE). +Wais = (KE+ PE)rmal +Q initial final Problems Work and Energy 1. A box is being moved to the right at a constant velocity v by a force P (parallel to v) along a level horizontal floor. The normal force is FN, the kinetic frictional force is fk, and the weight of the box is mg. (a) Draw a free-body diagram of this situation. +y +x (b) Decide which forces do positive, zero and negative work. Give your reasoning.

Expert Solution
Step 1

 

Physics homework question answer, step 1, image 1

The free body diagram gives all the forces acting on the body which is moving under a force with constant velocity v.

The gravitational force mg acts downwards and normal reaction exactly opposite to the force .The force of friction is opposite to the applied force.
