a crate of weight fg is pushed by a force P on a horizontal floor. (a) the coefficient of static friction is us, and P is directed at angle theta below the horizontal. show that the minimum value of P that will move the crate is given by P=usFgsectheta / 1-ustantheta (b) find the minimum value of P that can produce motion when us=0.400,Fg=100N and theta=0°,15.0°,30.0°,45.0°, and 60.0°.

Thank you in advance!
