Two boats are anchored in the harbor, separated by a horizontal distance of 24 m. The boats bob up and down as waves enter the harbor. When one boat is at its highest point, the other is also at its highest point and there is one wave crest between them. Each boat makes exactly 6 complete up-and-down cycles every 36.0 s. The vertical distance between a boat's highest and lowest position is 2.4 m. Determine the wavelength (m), frequency (Hz), period (s), amplitude (m), and speed (m/s) of the waves.

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.
