I think I do, that's the equation that the net work equals the change in kinetic energy correct? If that applies in this case, does that mean that I'd use this equation for this problem: W=KEf-KEi
Would the equation be set up like this: 4500J=2(1/2(100)v^2)-1/2((100)v^2)
Thanks for the guidance!
Here's my list of variables and things to account for:
m=100kg
Wnc=5000J
Wfriction=-500J
-Kinetic energy will be doubled (though I don't know how that plays into it exactly)
-I don't think there's any PE because it's on level ground
My idea of what the equation might be:
Wnc +1/2mv^2initial =...
