An aerospace engineering team is testing an orbital debris-clearing system in low-Earth orbit. A robotic capture probe, A, is sent to rendezvous with a piece of space junk, B, travelling in the same direction along the same straight path.
State the two physical quantities associated with motion that are conserved during a perfectly elastic collision.
The mass of Probe A is 520 kg and the mass of Debris B is 180 kg.
Calculate the momentum of both Probe A and Debris B before they collide.
Probe A = ______ kg m/s\text{kg m/s}kg m/s Debris B = ______ kg m/s\text{kg m/s}kg m/s
During the capture maneuver, the probe locks onto the debris so that they travel together as a single combined body. Calculate the speed of this combined body immediately after the collision.
Record your answer to 2 significant figures.
