Physics Quiz 4

[Ether]

Make the following changes to the original problem:

- The static coefficient of friction in the "Y" direction (the direction of the yellow arrow) is mu_y = 0.8

- The static coefficient of friction in the "X" direction (the direction of the blue arrow) is mu_x = 0.2

- The static coefficient of friction varies linearly with theta from mu=0.2 in the "X" direction to mu=0.8 in the "Y" direction as theta goes from zero (X direction) to pi/2 (Y direction).

Now find the value of Fx at which the block begins to slide.
