if 16,700 j of work is done to shoot the human cannonball down a 30.5m barrel, then how much force is applied to the person to fire them out the cannon ?

F=547.5

Explanation:

To Find the answer you have to remember the Formula for work. Work= Force* distance, because we are not finding work we have to fill in the variables or rearrange the formula to  Force= Work/Distance

Work= 16,700

Distance=30.5M

Force=?

So,

16,700=F*30.5

Now you isolate the variable by dividing both sides by 30.5

or

Force=16,700J/30.5M

and you get F=547.5

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
