Recoiling and Reviewing

DoNow: A 10 kg object is launched through a 100 kg tube. The object leaves the 2.5 m long tube with a muzzle speed of 500 m/s.
(a) Calculate the recoil velocity of the object.
(b) Calculate the change in KE or work done on the object.
(c) Calculate the average force acting on the object.
(d) Calculate the time the object in in the tube.
(notes) (video)

AIM: I can describe when and how to apply the Conservation of Momentum Law or Impulse-Momentum theorem to predict motion of objects in a collision or explosion type scenario.
