A 95 kg astronaut is on a spacewalk when the tether line to the shuttle breaks. The astronaut is able to throw a 15 kg oxygen tank in a direction away from the shuttle with a speed of 9.6 m/s, propelling the astronaut back to the shuttle. Assuming the astronaut starts from rest, find the final speed of the astronaut after throwing the tank. (Assume he threw the tank in the positive direction.)
