(E True (:3 False Question 2 2 pts To analyze the intermediate states ofa projectile's motion in a ballistic pendulum system, like the experiment conducted in class, Conservation of Energy and? or Consewation of Momentum is used. You had to choose which equation correctly applied given the conditions of the situation. In which case below can you NOT use Conservation of Momentum. Hint: In which of the situations stated below would momentum not be conserved. (El Net external forces ec|ua| zero {There is no net external force] 0 Net external forces do not equal zero {There exists a net external force}
