A couple of astronauts agree to rendezvous in space after hours. Their plan is to let gravity bring them together. She has a mass of 66.0kg and he a mass of 76.0kg , and they start from rest 21.0m apart.
Part A Find his initial acceleration.
Part B Find her initial acceleration.
Part C If the astronauts' acceleration remained constant, how many days would they have to wait before reaching each other?
