Solve the problem.
-How much work does it take to slide a box 46 meters along the ground by pulling it with a $72 \mathrm {~N}$ force at an angle of $15 ^ { \circ }$ from the horizontal?
A) 3312 joules
B) 69.55 joules
C) 3199 joules
D) -2516 joules

Question

Quizplus · Accepted Answer

Work done is given by the formula:
Work = force x distance x cos(angle)

In this case, force = 72 N, distance = 46 m, and angle = 15 degrees.

Work = 72 N x 46 m x cos(15 degrees)
Work = 3199 joules

Therefore, the correct answer is C.
