A 9 kg asteroid is traveling through space at 2.5 m/s toward a spaceship. To avoid a collision, an astronaut, with the help of a backpack rocket, exerts a force of 25N on the asteroid in the opposite direction for 4 seconds. a) Find the asteroid s final speed. m/s (Hint: Assume the initial speed f the asteroid is in the positive x direction.) b) How long should she have pushed in order to just stop the asteroid? Time to stop asteroid = seconds
