Question

Example The force shown has magnitude Fr= 20 N& makes an angle 0 = 30° to the ground. Calculate the work done by this force when the wagon is dragged a displacement d = 100 m along the ground.

Answer 1

The work done by a force is calculated using the formula: Work = Force x Displacement x cos(theta). Using the given values, the work done is 1732 J.

Step-by-step explanation:

The work done by a force can be calculated using the formula:

Work = Force x Displacement x cos(theta)

Given that the force has a magnitude of 20 N and makes an angle of 30° to the ground, we can calculate the work done as:

Work = 20 N x 100 m x cos(30°)

Work = 20 N x 100 m x 0.866

Work = 1732 J
