**DISCUSSION THREAD**

Any questions??

*Four-step plan:*

* Step 1* - FBD: Draw a free body diagram of the crate.

* Step 2* - Kinetics: Write down the Newton/Euler equations for the crate. Be careful with your moment equation. Since the crate has no fixed points, you need to sum moments about the center of mass of the crate.

* Step 3* - Kinematics: Crate does not tip, so

*α = 0*.

* Step 4* - Solve

Can we assume that the block have zero acceleration in the x direction(along with inclinded surface)

I don't think so. Also, in the animation the crate clearly slows down and speeds up...

In the solution video there is a variable "N" that is used several times. I cannot figure out what this variable is supposed to represent. Does anyone know what it is?

In the solution video, forces labeled "N" with a subscript refers to normal contact forces on the crate by the incline.
