Solve the all parts of following question:
Question: A winch is used to drag a 315N crate up a ramp at a constant speed of 60.0cm/s by means of a rope that pulls parallel to the surface of the ramp. The rope slopes upward at 35.0m above the horizontal, and the coefficient of kinetic friction between the ramp and the crate is 0.300.
Part A: What is the tension of the rope?
Part B: If the rope were to suddenly snap, what would be the acceleration of the crate immediately after the rope broke?
I need help to find the acceleration of the crate immediately after the rope broke.
