Question 29
Easy

Figure 1 shows a worker pulling a heavy crate up a ramp onto a loading platform.

A diagram showing a right-angled triangle representing a ramp. The horizontal distance of the ramp along the ground is labeled 8.0 m. The vertical height of the ramp from the ground to the platform is labeled 1.5 m. The length of the sloped surface of the ramp is labeled 8.1 m. A worker is shown pulling a crate up along the sloped surface.

Explain which of the three distances shown in Figure 1 should be used to calculate the work done against the force of friction between the crate and the ramp.
