Astronaut Catch Imagine that you are hovering next to the space shuttle in earth-orbit and your buddy of equal mass who is moving 4 m/s (with respect to the ship) bumps into you. If she holds onto you, then how fast do the two of you move after the collision? A question like this involves momentum principles. In any instance in which two objects collide and can be considered isolated from all other net forces, the conservation of momentum principle can be utilized to determine the post-collision velocities of the two objects. Collisions between objects are governed by laws of momentum and energy. When a collision occurs in an isolated system, the total momentum
