Question

A 25 newton force applied on an object moves it 50 meters. The angle between the force and displacement is 40.0°. What is the value of work being done on the object?
0 joules
9.6 × 102 joules
1.2 × 103 joules
-9.6 × 102 joules
-1.2 × 103 joules

Answer 1

\[W=\int\limits_{0}^{50}F*cos(40.0^o)dx\]\[W=50*25*cos(40.0^o)\]\[\boxed{\boxed{W\approx957.56~J}}\]

Answer 2

\[W\approx957.56~J\approx9.6\times10^2~J\]

Answer 3
