Matthew pulls his little sister Sarah along the horizontal ground in a wagon.He exerts a force on the wagon of 60.0 N at an angle of 37.0° above the horizontal.If he pulls her a distance of 12.0 m,how much work does Matthew do?

Question

Quizplus · Accepted Answer

The work done by Matthew can be calculated using the formula:

work = force x distance x cos(theta)

where force is 60 N, distance is 12 m, and theta is the angle between the force and the direction of motion (37 degrees in this case).

Plugging in the values, we get:

work = 60 N x 12 m x cos(37 degrees)
     = 575 J

Therefore, the answer is C, 575 J.
