A winch is used to frag a 375 N crate up a ramp at a constant speed of 0.75 m/s by means of a rope that pulls parallel to surface of the ramp. The rope slopes at 33 deg. above the horizontal, and the coefficient of kinetic friction between the ramp and the crate is 0.25. (a) What is the tension in the rope? (b) If the rope were suddenly to snap, what would be the acceleration of the crate immediately after the rope broke?
