Two spacecraft are 23,500 m apart and moving directly toward each other. Spacecraft#1 has velocity 520 m/s and accelerates at a constant -15.5 m/s2. They want to dock, which means they have to arrive at the same position at the same time with zero velocity. These aliens are watching in anticipation. (a) What should the initial velocity of the spacecraft#2 be? (b) What should be #2 constant acceleration? (Hint start with spacecraft #1)
