Calculus application problem (involving force and work)?

Question

A toy wagon is pulled by exerting a force of 40 pounds on a handle that makes a 30degree angle with the horizontal. Find the work done in pulling the wagon 75 feet

Answer 1

Calculus not needed force and distance are constants.

Horizontal force = 40 cos 30 deg = 34.6 lb

34.6 lb * 75 ft = 2598 ft-lb

Answer 2

Work done = (40cos 30°).(75) ft.lbs
Work done = 2598 ft lbs (to nearest whole number)
