Hi! Do you know the definition of work?

anonymous · Answer

Change in kinetic energy

theeric · Answer

That's one! So let's apply that.
I don't know what "powered by a mousetrap" means...
But I know that coasting isn't much of a change in KE! Well, friction applies, so friction does some work. But....

Do you know what it means by that mousetrap? If it's powered, I'd think that means it's KE is changing more...
