Question

In Example 2, which included friction, what was the net work done on the box?
Options
A 5.2 × 10² J
B -4.3 × 10² J
C 90.0 J
Correct Answer
D 0 J
Correct Answer

Option C is the correct answer.

Detailed Explanation

The net work is the sum of the work by the applied force (5.2×10² J), the work by friction (-4.3×10² J), and zero work by normal and gravity forces. The total is 90.0 J.

Hint

W_net = W_applied + W_friction + W_N + W_G.
