Question

A mover is loading a 253 kg crate of hammers onto a truck. the upward force on the crate is 2470 n, and 3650 j of work are required to raise the crate from the pavement to the truck bed. how far is the crate lifted?

Answer 1

To determine the distance the crate is lifted, divide the work done (3650 joules) by the upward force (2470 newtons). The resulting distance is approximately 1.48 meters, which is the height the crate is lifted onto the truck bed.

Step-by-step explanation:

The question involves the concept of work done when lifting an object. Work is defined in physics as the product of the force applied to an object and the distance over which that force is applied. The formula for work is W = F × d, where W is work in joules, F is force in newtons, and d is distance in meters.

To find out how far the crate is lifted, we can rearrange the work formula to solve for distance d by dividing the work done by the force: d = W / F. Given that the work done (W) is 3650 joules and the force (F) is 2470 newtons, the distance can be calculated as d = 3650 J / 2470 N, which yields approximately 1.48 meters. This indicates that the crate is lifted 1.48 meters onto the truck bed.
