Unformatted text preview: (last) (first) DL Sec# c) Before the craft dropped into orbit, the velocity in our frame was just it’s initial speed, v c =40km/s . After it comes back out of orbit, it’s velocity is the same as point b. If the craft’s 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...
