*13-16. The man pushes on the 60-lb crate with a force F. The force is always directed down at 30 from the horizontal as shown, and its magnitude is increased until the crate begins to slide. Determine the crates initial acceleration if the coefficient of static friction is fis = 0.6 and the coefficient of kinetic friction is /x* = 0.3.
