Answer to Question #150436 in Physics for lol

Question

1. Dogs pull a sled 755 meters using 85500  Joules of energy. Calculate average force.

Answer 1

By definition, the work is:

$$W = Fs$$

where $F$ is the force acted on a distance $s$. Since $s = 755m$, and $W = 85500J$, the force is:

$$F = \dfrac{W}{s} = \dfrac{85500J}{755m} \approx 113.2N$$

Answer. 113.2N.
