You are visiting Six Flags Over Texas and are riding the latest rollercoaster. The coaster full of people (mass of 1200 kg) travels 16 m/s down the first hill. How much KE does the coaster have?
answer

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?
