Anasa explorer spacecraft with a mass of 1,000 kg takes off in a positive direction from a stationary asteroid. if the velocity of the spacecraft is 250 m/s and the asteroid is pushed back –25 m/s, what is the mass of the asteroid? assume there is no net force on the system.
Answers: 2
is given by the following equation: 
(1) 
is the mass of the object 
is the velocity of the object
(2) 
is the mass of the spacecraft
is the mass of the asteroid
is the initial velocity of the spacecraft
is the initial velocity of the asteroid (because we are told the asteroid is stationary, as the spacracft is on the sateroid it remains stationary as well)
is the final velocity of the spacecraft
is the final velocity of the asteroid
(3) 
(4) 
This is the mass of the asteroid
