Q1. A weight of 1200 N rests on a lever at a point 0.50 m from a support. On the same side of the support, at a distance of 3.0 m from it, an upward force with magnitude F is applied. Neglect the weight of the board itself. If the system is in equilibrium, what is F?

Q2. A 35.0 g bullet moving at 475 m/s strikes a 2.5 kg bag of flour that is on ice, at rest. The bullet passes thru the bag and exits at 275 m/s. How fast is the bag moving when the bullet exits?

Q3. A 120 granite cube slides down a 45 frictionless ramp. At the bottom, just as it exits onto a horizontal table, it collides with a 210 steel cube at rest.
