An astronaut in orbit outside an orbiting space station throws her 800.0-g camera away because it jams. if she and her space suit together have a mass of 100.0 kg and the speed of the camera is 12.0 m/s, A. what will be the speed of the astronaut after throwing the camera? B. How far away from the space station will she be in 5 minutes? c. a 5.0-kg lump of clay that is moving at 10.0 m/s to the left strikes a 6.0-kg lump of clay moving at 12.0 m/s to the right. the two lumps stick together after they collide. Find the final speed of the lump clay.

you can use conservation of linear momentum to find speed of astronaut. Pin=Pfin (of course momentum is a vector quantity)

How?

The initial linear momentum is zero at space reference frame. Therefore the final linear momentum has to be zero. So Pin=0 Pfin=(mass of the camera)*(velocity of the camera) + (mass of the astronaut)*(velocity of the astronaut) then Pin=Pfin so you can find from here what velocity is.
