A family is moving from Pennsylvania to Connecticut. The movers are using a ramp to load boxes onto the truck. The advantage of the ramp is to reduce the—

• force needed to raise the boxes by increasing the distance the box is moved

• time needed to raise the boxes by reducing the distance the box is moved

• work needed to raise the boxes by increasing the distance the box is moved

• effort needed to raise the boxes by reducing the distance the box is moved

Paul’s family is moving across town, so his father rented a moving truck for the day. A ramp pulls out of the truck bed. The bed of the truck is 1 m high, and the ramp is 3 m long. Paul makes two statements about the truck ramp:

Statement 1: The ramp is an inclined plane, and we will have to move the boxes a longer distance to get them into the truck than if we lifted them straight up.

Statement 2: Using the inclined plane will require less effort.

• Statement 1 is true and statement 2 is false.

• Statement 1 and 2 are both true.

• Statement 1 is false and statement 2 is true.

• Statement 1 and 2 are both false.
