her total mass = 110 + 20.8 - 5 = m
m v = 5 * 16.4
a space shuttle astronaut has a mass of 110 kg with her spacesuit on. She is on a spacewalk and picks up a full can of spray with a mass of 20.8kg. Relative to the space shuttle, she is at rest. She then holds the can directly in front of her center of mass to avoid rotation and releases 5.0kg of spray at a speed of 16.4m/s. Her speed, relative to the space shuttle, when she has stopped spraying is approximately a.bc m/s.
