The force that is actually being used to push the mower along the ground is 200 N. This is because the force of 250 N is not entirely in the direction of the ground. The force is actually at an angle of 40° west of North, so only a portion of it is in the direction of the ground.

To calculate the force that is actually being used to push the mower along the ground, we can use the following formula:

Code snippet

Force along ground = Force applied * cos(angle)

where:

• Force along ground is the force that is actually being used to push the mower along the ground

• Force applied is the force that is being exerted by the student

• Angle is the angle between the force and the ground

In this case, the force applied is 250 N, the angle is 40°, and the force along the ground is:

Code snippet

Force along ground = 250 N * cos(40°) = 200 N
