Question

3. If I lift a 10-pound weight above my head with a force of 20 N and it travels

.5 meters, what work was done?
4.
I pushed a box with a force of 30 N across the floor. If the work done is 60
J, what distance did the box travel?
5. The work completed on moving an object was 450 J, if the distance
traveled was 10 meters what was the force applied to the object?

Answer 1

Work is the product of force and distance. We can use the work formula to find the work done, distance traveled, or force applied in different scenarios.

Step-by-step explanation:

Work is defined as the product of force and distance. In the first question, the work done is given by the formula:

work = force * distance

So, in this case, the work done is 20 N * 0.5 m = 10 J.

In the second question, the work done is given and we need to find the distance traveled. We can rearrange the work formula to solve for distance:

distance = work / force

So, in this case, the distance traveled is 60 J / 30 N = 2 m.

In the third question, the work done is given and we need to find the force applied. We can rearrange the work formula to solve for force:

force = work / distance

So, in this case, the force applied is 450 J / 10 m = 45 N.
