a. Draw a free body diagram of all the forces on the crate.
b. Write out one equation for the y component of the resultant force. Hint: The crate
does not move in the y direction.
Write out one equation for the x component of the resultant force. Hint: the crate
moves in the x direction.
C.
d. Determine the Normal force.
