Unformatted text preview: (last) (first) DL Sec# c) Before the craft dropped into orbit, the velocity in our frame was just its initial speed, v c =40km/s . After it comes back out of orbit, its velocity is the same as point b. If the crafts mass is 2000kg, find the impulse imparted to the craft by the planet. Keep in mind, impulse is a vector and is equal to the vector difference of the momenta! b) If we wanted to model this as a collision, what kind of collision would this be? (hint: Think about energy) Explain in 1 small sentence. v c v c a b V c a b VS V c V P V P =0 a V P V c V P V c...
