Ben and jerry compete in a 1.00 km race. Ben's strategy is to run the first 600 m of the race at a constant speed of 4.00 m/s, and then accelerate to his maximum speed of 7.50 m/s, which takes him 1.0 min, and then finish the race at that speed. Jerry decides to accelerate to his maximum speed of 8.00 m/s at the start of the race and to maintain that speed throughout the rest of the race. It takes Jerry 3.00 min to reach his maximum speed Assuming all accelerations are constant, who wins the race?

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?
