a. if i use 100N of force and move 3 meters, how much work is this? b. if it takes 90 seconds to get there, how much power did i exert?

How much works is done by an object that uses 100N force and a distance of 3.Om

a) Work = Force x Distance

b) Power = (Work done)/(Time required to do it)

To calculate work, we use the formula:

Work = Force × Distance

a. If you use 100N of force and move 3 meters, the work done can be calculated as:

Work = 100N × 3m
= 300 Joules (J)

So, the work done is 300 Joules.

b. Power can be calculated using the formula:

Power = Work / Time

If it took 90 seconds to get there and the work done is 300 Joules (as calculated in part a), we can determine the power exerted as:

Power = 300J / 90s
= 3.33 Watts (W)

Therefore, you exerted 3.33 Watts of power.
