Question

If 18,600 J of work is done to shoot he human cannonball down a 4.25 m barrel, then how much force is applied to the person to fire them out of he cannon?

Answer 1

We will have the following:

`18600J=F\cdot4.25m\Rightarrow m=(18600J)/(4.25m)`
`\Rightarrow F=(14400)/(17)N\Rightarrow F\approx4376.47N`

So, the force applied is 14400/17 N, that is approximately 4376.47 N.
