Your motorbike breaks down five Km from your home. You use 400 N for the entire 60 minutes that it takes you to push this motorbike home. How powerful were you? How many Watts?

Answer 1

To calculate power, we can use the formula:

Power (P) = Force (F) x Distance (d) / Time (t)

Given:
Force (F) = 400 N
Distance (d) = 5 km = 5000 m
Time (t) = 60 min = 60 x 60 = 3600 s

Substituting the values into the formula:

Power (P) = 400 N x 5000 m / 3600 s

Power (P) = 2000 N·m / 3600 s

Power (P) = 0.5556 N·m/s

Power (P) = 0.5556 Watts

Therefore, you were exerting a power of 0.5556 Watts to push your motorbike home.
