3. An air hockey puck is moving to the right along a horizontal air table (so friction is completely negligible). You apply a (not necessarily constant) force to the left that stops the puck and eventually turns the puck around. See the figure below. At the final time, the puck is now traveling to the left but with a speed less than the initial speed. If the puck is your system, is the work done by your force, positive, negative, or zero. Explain.

Two, unattached boxes are accelerated by a force, F, as in the figure below. The coefficient of static friction between the boxes is 0.9 and the coefficient of kinetic friction between the boxes is 0.5. What's the minimum force, F, required such that the smaller box does not slip down the bigger box? Mass M = 9.8 kg and mass m = 2.7 kg. Assume that there is no friction between the ground and the boxes.

Mason is is trying to keep a door open using a door stopper. That door is solid, and it has a mass of 18.3kg. The door closer is connected 26.2cm away from the hinge, and pulls with a force of 123N. The door stopper provides a static friction force of 13.2N, and a kinetic friction force off 11.8N. Find the angular acceleration (as a vector) of the door.
A ball is rolled horizontally on a smooth, frictionless table with velocity v0v0. The table is at a height hh above the ground. A tube of length xx is protruding from the end of the table as shown in the attached figure. The tube is not smooth, so the ball decelerates constantly with the acceleration being aa in magnitude. Once the ball leaves the tube, the ball falls towards the ground. a) Find the distance ℓℓ between the point at which the ball lands on the ground and the base of the table (see the figure below). Your answer may depend on v0v0, xx, gg, hh and aa. b)For what value of xx is ℓℓ maximum?
