1. Press "Fire" and observe the simulation
2. Reset and select any values for "Mass of bullet",  "initial velocity of bullet", and "mass of wood block"
3. Using conservation of momentum during the collision, and conservation of mechanical energy after the collision, predict the maximum height of the wooden block.
4. Press "Fire" again. Measure the change in height using the ruler on the right. Does this match your predicted value?
