Question

A traveler pulls a suitcase, as shown in the figure. (image below)

The force acting on the handle is 35 N at an angle of θ = 30°. How much work is done if the traveler moves 110 meters? Round to the nearest whole number.

1,893 Nm
1,925 Nm
2,703 Nm
3,334 Nm

Answer 1

3334 N·m

Explanation:

Work is the product of force and distance. The force used in the product is the force that is in the direction of motion.

__

The horizontal component of the applied force is ...

F = (35 N)cos(30°) ≈ 30.311 N

Then the work done is ...

W = Fd

W = (30.311 N)(110 m) = 3334 N·m
