All right, so let's say we have a car going up a small incline of five degrees.
00:07
And as it's going up the incline, we have a variety of forces acting on it.
00:11
So we have the weight, of course, going straight down.
00:14
We have the normal force going this way.
00:18
We're told a frictional force acts against it with a magnitude of 524 newtons.
00:26
And there's another force f along the plane, presumably.
00:31
That generates the motion of the car.
00:33
So we want to know if it travels a distance along the ramp of 290 meters, what should f be so that the network done on the system is 150 ,000 joules.
00:47
So the network on the system, or better yet, let's find the net force...
