All right, so let's say we have a crate being pushed up an inclined plane that is inclined at an angle theta, which is 33 degrees.
00:12
And we have a crate like this, but the force being applied is in this direction.
00:16
So it's horizontal, and it has a magnitude of 600 newtons.
00:21
And the ramp is frictionless, and the mass of our block is 83 kilograms.
00:26
So we want to draw a free body diagram here.
00:28
So the weight is going to go straight down like this, and then we can break that up into two components.
00:34
This is m .g.
00:35
Sine theta, and then m .g.
00:38
Cosine theta, which is our normal force.
00:41
So that's our free body diagram, and then, of course, we have our force f going in that direction.
00:46
So part b asks, what's the magnitude of the weight of the crate? so this is just m .g...
