I derived the equation F(CosTheta-.3SinTheta) > 10. With 2 variables (F and theta), how would this equation be solved to find the angle?

I'm unsure as to how you got that inequality. Does u. mean Mu? A hint that was given to solve this problem was that sin^2Theta + cos^2Theta = 1.

Yes but how would I find the angle where no matter what force is applied in the parallel components acting up, the block wouldn't move?

Homework Statement What force is needed to move a 10 pound block up a vertical wall at a constant speed by pushing at an angle of 53 degrees with the vertical? Mu=0.3 At what minimum angle with the vertical would you be unable to push the block at all regardless of how large the force...

Is it possible to assume that right when the ball passes the fence, that the initial velocity is 0 if I divide the problem into two? (One up to the fence, and one after the fence)

Homework Statement A ball is shot from a slingshot and clears a 10 meter fence 130 meters from the point of being flung and lands 10 meters behind the fence. What is the initial velocity of the ball? Assume the ball was caught at the same level it was kicked (delta Y=0). Homework...
