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 60.0 kg and he a mass of 76.0 kg , and they start from rest 15.0 m apart. A) Find his initial acceleration. B) Find her initial acceleration. C) If the astronauts' acceleration remained constant, how many days would they have to wait before reaching each other? (Careful! They both have acceleration toward each other.)
You have a 10-kg table with each leg of mass 1.0 kg Acˆ'total mass 14 kg. If you place a 5.0-kg pot of soup in the back right corner of the table (Figure 1) , where is the table's center of mass? Assume that the size of the soup bowl and thickness..
