1) an 80 kg spacewalking astronaut pushes off a 640kg satellite, exerting a 100 N force for the .50 s it takes him to straighten his arms. How far apart are the astronaut and the satellite after 1 min?
2)A 20,000 kg rocket has a rocket motor that generates 3.0x10^5 N thrust.
a) What is the rocket's initial upward acceleration?
b) At an altitiude of 5.o km the rocket's acceleration has increased to 6.0 m/s^2. What mass of fuel has it burned?
