Here we're going to look for the distance along the incline d.
00:02
This is related to the height ascended.
00:04
We know that we have a relationship, delta height, delta h, would be equal to d sine of theta, where d is the distance along the incline.
00:14
And we know that, again, on the incline, the force normal is equaling mg cosine of theta.
00:20
Therefore, we can say that the force of kinetic friction would be equal to the coefficient of kinetic friction, mg cosine of theta.
00:28
And so we can say that no, with equation 833, knowing that the work done is equaling zero joules, we can say that zero would be equal to the final kinetic energy.
00:42
This would be minus the initial kinetic energy plus the change in potential energy plus the change in thermal energy.
00:51
So we can then say that zero would equal zero minus the initial kinetic energy, plus mgd sine of theta...
