0.002 kg bullet, moving at 538 m/s strikes a 0.250 kg piece of wood at rest on a frictionless table. The bullet sticks in the wood and the combined mass moves slowly down the table. a. Using the conservation of momentum formulas, calculate the speed of the objects after the collision b. Calculate the total kinetic energies of the objects before the collision and after the collision c. Compare them. Is energy conserved in this type of collision? d. What type of collision is this? totally elastic
