A 94 astronaut and a 1200 satellite are at rest relative to the space shuttle. The astronaut pushes on the satellite, giving it a speed of 0.25 directly away from the shuttle. Sevenandahalf seconds later the astronaut comes into contact with the shuttle.What was the initial distance from the shuttle to the astronaut?

physics 
bobpursley,
velocityastronaut= distance/(7.5min*60sec/min)
now, conservation of momentum.
1200kg*.25m/s=94kg*distance/(7.5*60sec)
solve for distance.
YOu did not put units on numbers in your problem statement. In the Physical sciences, numerals are meaningless without units.
