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

Answer:

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

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:

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