Physics HW Help?
A boy is pulling his sister in a wagon, as shown in the figure. He exerts a force of F = 59.5 N at an angle of 30°.
How much work does the boy do pulling his sister, in joules, if he pulls her 28 m?

Assuming level ground,
work = F • d = 59.5N * 28m * cos30º = 1484 J
which ought to be rounded to 1500 J imo.
