2) Two astronauts, one of mass 60 kg and the other 82 kg, are initially at rest in outer space. They then push each other apart. How far apart are they when the lighter astronaut has moved 13 m?
____m
____m
-
Velocity * mass = energy, and the energy in each must be equal
if time is set to a certain amount, then we can replace velocity with distance because they both started moving at the same time.
60*13 = 82*x
x = 9.51m
Distance apart = 9.5m + 13m = 22.51m
