  1. Science Starter! An astronaut at rest in space fires a thruster pistol that expels 35 g of hot gas at 875 m/s. The combined mass of the astronaut and pistol is 84 kg. (a) How fast and in what direction is the astronaut moving after firing the pistol? (b) How does the final momentum of the gas compare to the final momentum of the astronaut?

  2. Two Dimensional Collisions(Glancing Collisions) • Momentum is conserved in “x” and “y” directions • 2 step problem
