Sally finds herself stranded on a frozen pond so slippery that she can't stand up or walk on it. To save herself, she throws one of her heavy boots horizontally, directly away from the closest shore. Sally's mass is 60.0 kg, the boot's mass is 5.0 kg, and Sally throws the boot with speed equal to 30.0 m/s. For all parts, assume the ice is frictionless. 1) What is Sally's speed immediately after throwing the bo
