Question

A horizontal force of 30 N is used to move a 2 kg mass through a distance of 5.0 m in the direction of the force. The work done by the force is

Answer 1

Answer:

Work = force x displacement x cos theeta

W = (30 N) * (5 m)* cos(0 degrees) = 150 J

The force and the displacement are given in the problem statement. It is said (or shown or implied) that the force and the displacement are both rightward. Since F and d are in the same direction,the angle is 0 degrees.
