Question

Suppose a force of 100 newtons is used to push an object a distance of 5 meters in 15 seconds. Find the work done and the power for this situation

Answer 1

The answers are: `L=500J and P=33.3W`.

To answer to the questions these formulae are needed:

`L=vecF*vecs`: where the `*` is the scalar product;

and:

`P=L/t`

So:

`L=100N*5m=500J`

(I supposed that the angle between `F and S` is 0);

and:

`P=(500J)/(15s)=33.3W`.
