Q. A 66-{rm kg} skier speeds down a trail, as shown in the figure . The surface is smooth and inclined at an angle of 22 ^circ with the horizontal. Find the magnitude of the net force acting on the skier.

Q. A 22kg box slides 4.0m the frictionless ramp that is angled at 30* above the horizon. The box collides with a spring whose spring constant is 210. What is the max compression of the spring?
