Question

A rope pulls on a metal box at an angle of 40 degrees with a force of 255 N. The box moves horizontally for 15.0 m. How much work was done on the box?

A. 255 J
B. 2,930 J
C. 2,460 J
D. 3,830 J

Answer 1

as in a previous exercise, we have to apply the subsequent formula:
\[W = Fd\cos \left( {40} \right) = 255 \times 15 \times \cos 40\]

Answer 2

2930 J is our solution?
