Valentina, a Russian cosmonaut, exits her ship for a space walk. When she is 15 m from the ship and floating motionless, her tether catches on a sharp piece of metal and is severed. Valentina quickly reacts by tossing her 2 kg camera away from the spaceship with a speed of 12 m/s. a). How fast will Valentina, whose combined mass with spacesuit is 188 kg, float toward the spaceship? (Round answer to nearest hundredth). b) Assuming that the space ship remains at rest with respect to her, How long (in seconds) will it take for her to float back to the ship ?
