Two 140-kg satellites collide at an altitude where g = 8.7 m/s2 , and the collision
Chapter 9, Problem 25(choose chapter or problem)
Two 140-kg satellites collide at an altitude where g = 8.7 m/s2 , and the collision imparts an impulse of 1.8*105 N# s to each. If the collision lasts 120 ms, compare the collisional impulse to that imparted by gravity. Your result should show why you can neglect the external force of gravity.
