SOMEONE PLEASE PLEASE HELP PLEASE HELP 1. You pull a wagon carrying your younger brother 1000 meters (1 km) to the store using
20 newton's of force the whole way. It takes you 15 minutes to get there. How much
power did you generate, in joules per minute? In watts?

22.2 W

Explanation:
First of all, we calculate the work done by moving the wagon, using the formula:

where
F = 20 N is the magnitude of the force
d = 1000 m is the displacement of the wagon
is the angle between the direction of the force and of the displacement (assuming the force is applied in the direction of motion)
Substituting, we find

Now we can find the power generated, which is equal to the ratio between the work done and the time taken:

where
W = 20,000 J
t = 15 min = 900 s
Substituting,

And the same value in Joules/second (remember that 1 Watt = 1 Joule/second)
