1. suppose you have a pipe producing standing sound waves. two adjacent harmonics of standing waves (i. e., no standing waves in between these) have wavelengths 2.000 meters and 1.500 meters.
which wavelength corresponds to a higher mode?

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.
