Q1. A winch is used to drag a 375 N crate up a ramp at a constant speed of 0.750 m/s by means of a rope that pulls parallel to surface of the ramp. The rope slopes at 33 degree above the horizontal, and the coefficient of kinetic friction between ramp and 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?

Q2. In a head-on collision, the car stops in 0.279 from a speed of 16. The driver has a mass of 68, and is, fortunately, tightly strapped into his seat. What force is applied to the driver by his seat belt during that fraction of a second?
