A winch is used to drag a 345 N crate up a ramp at a constant speed of 79.0 cm/s by means of a rope that pulls parallel to the surface of the ramp. The rope slopes upward at 27.0 ? above the horizontal, and the coefficient of kinetic friction between the ramp and the crate is 0.250.

Part A What is the tension in the rope?

Part B If the rope were suddenly to snap, what would be the acceleration of the crate immediately after the rope broke?
