Two astronauts, one of mass 57 kg and the other 86 kg ,are initially at rest together in outer space. They then push each other apart.

Part A

How far apart are they when the lighter astronaut has moved 12 m ?

Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

The center of mass should not move.
Therefore m1 d1 = m2 d2
d2 = m1 d1/m2 = 57 * 12/86 = 7.95 m
Separation = d1 + d2 = 12 + 7.95 = 19.95 m
d = 19.95 m
