Question

If 16,700 J of work is done to shoot the human cannonball down a 3.05 m barrel, then how much force is applied to the person to fire them out the cannon?

Answer 1

`5,480\:\text{N}`

Step-by-step explanation:

The formula for work is given by
`W=F\Delta x`, where
`F` is the force applied over a distance of
`\Delta x`.

Plugging in given values, we get:

`16,700=F\cdot 3.05,\\F=(16,700)/(3.05),\\F\approx \boxed{5,480\:\text{N}}`(three significant figures).
