When the crest of a wave meets the trough of another wave, the amplitude of the overlapping waves is smaller than either of the two original waves. How do you think this affects the amount of energy traveling through each wave? Explain your reasoning. (Hint: Consider what happens to each wave after they meet and overlap.)

During a medieval siege of a castle, the attacking army uses a trebuchet to hurl heavy stones at the castle walls. if the trebuchet launches the stones with a velocity of at an angle of 50.0°, (a) how long does it take the stone to hit the ground? (b) what is the maximum distance that the trebuchet can be from the castle wall to be in range? (c) how high will the stones go? show all your work.
