Use the diаgrаm аnd pоsitiоn vectоrs as a function of time from the previous problem. If aircraft A has a mass of 100,000 Kg and aircraft B has a mass of 200,000 Kg And both aircraft collide and stick to each other (so they move with the same velocity vector after the collision, an inelastic collision) (a) Determine the velocity vector of the aircraft stuck together after the collision (b) If the aircraft are 10,000m high when they collide how long before they hit the ground? (c) Assuming the x and y velocity found in part (a) remains constant as the aircraft fall, how far in the x and y directions do the aircraft travel from when they collided, to when they hit the ground (d) When they hit the ground and their velocity goes to zero, their kinetic energy suddenly goes to zero, where did that energy go??
