Question 6

A worker pushes a 50 kg box across a rough horizontal floor with a constant applied force of 200 N. If the coefficient of kinetic friction between the box and the floor is 0.2, and the box moves 10 meters, what is the net work done on the box? (Take acceleration due to gravity g = 10 m/s²)

Accepted Answer

A. 1000 J — The net work done on an object is the sum of work done by all forces acting on it. The applied force does W_applied = F_applied × d = 200 N × 10 m = 2000 J. The normal force is N = mg = 50 kg × 10 m/s² = 500 N. The kinetic frictional force is F_friction = μ_k × N = 0.2 × 500 N = 100 N. The work done by friction is W_friction = -F_friction × d = -100 N × 10 m = -1000 J (negative as it opposes motion). Therefore, the net work done is W_net = W_applied + W_friction = 2000 J - 1000 J = 1000 J. This net work done also equals the change in kinetic energy of the box.

Answer

B. 2000 J

Answer

C. 500 J

Answer

D. 0 J
