Pt 1. Amanda lifts a crate into the back of her truck. She exerts a force of 200N distance of 1.2m. Calculate the amount of work (joules) done on the crate. Pt 2. Amanda then used an inclined plane to push the same crate into the truck She exerts a force of 77.5N a distance of 3.1m. What is the work (joules) done

Answer (Part 1):

620 joules

Explanation:

Work is done when force is applied on an object over a distance. It is measured in joules.

Formula

Thus, Work = Force x distance

Since, Work = ? (unknown value)

Given:

Force = 200N

Distance = 1.2 meters

So,

Work = 200N x 3.1 meters

= 620 joules

Thus, Amanda did a work of 620 joules on the crate.

Answer (Part 2):

240.25 joules

Explanation:

Work is done when force is applied on an object over a distance. It is measured in joules.

Formula

Thus, Work = Force x distance

Since, Work = ? (unknown value)

Given:

Force = 77.5N

Distance = 3.1 meters

So,

Work = 77.5N x 3.1 meters

= 240.25 joules

Thus, Amanda did a work of 240.25 joules on the crate.

Hope this helps! :)

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
