Q11: the man pushes on 60 lb. crate with a force F. The force is always directed down at 30o from the horizontal as shown, and its magnitude increased until the crate begins to slide. Determine the crate's initial acceleration if the static coefficient friction is us = 0.6 and the kinetic coefficient friction is µk = 0.3 %3D
