Question

A sled is pulled along a level path through snow by a rope. A 35-lb force acting at an angle of 35° above the horizontal moves the sled 50 ft. Find the work done by the force. (Round your answer to the nearest whole number.)

Answer 1

1433.51 lb-ft

Explanation:

A sled is pulled along a level path through snow by a rope. A 35 lb force acting at an angle of 35° above the horizontal moves the sled 50 ft. Find the work done by the force. Round your answer to the nearest whole number.

horizontal force = 35×cos(35°) lb

displacement = 50 ft

work = 35×cos(35°)×50 = 1433.51 lb-ft
