George has a mass of 30 kg. he sits 1.4 m from the axis of rotation of a see-saw. if susie has a mass of 27 kg, how far from the axis of rotation should she sit on the other side of the see-saw to keep it in static equilibrium? assume the center of mass of the see-saw is above the axis of rotation. g

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
