Question

How does using a ramp make work easier when loading a piano onto a truck three feet above the ground

Answer 1

The ramp on an automobile transport truck is used to lift cars high into the air. An inclined plane makes it easier to raise something heavy, like a rock. Instead of lifting the rock straight up, you can raise it from its original location with less force by pushing it up a ramp.

Answer 2

The correct answer is

D. It allows a smaller force to be applied over a longer distance.
