BTW, brainliest would be greatly appreciated, I only need one more before I advance, thanks!
Also, I may have done something wrong, please tell me if it's incorrect!
At start: PE only
At end: KE and energy lost to friction
PE = KE + E
E = PE - KE
= mgh - (1/2)mv^2
= (40)(9.8)(12) - (.5)(40)(10)^2
= 2704J
1 + 1x
OR
1 + x
They mean the same thing! Hope this helps!
