A fisherman notices that his boat is moving up and down periodically, owing to waves on the surface of the water. It takes 3.50s for the boat to travel from its highest point to its lowest, a total distance of 0.640m . The fisherman sees that the wave crests are spaced 7.80m apart. How fast are the waves traveling? in m/s What is the amplitude of each wave? in m If the total vertical distance traveled by the boat were 0.300 m, but the other data remained the same, how fast are the waves traveling ? in m/s If the total vertical distance traveled by the boat were 0.300 m, but the other data remained the same, what is the amplitude of each wave? in m
A 15.00 block is attached to a very light horizontal spring of force constant 450 and is resting on a smooth horizontal table. Suddenly it is struck by a 3 stone travelling horizontally at 8 to the right, whereupon the stone rebounds at 2.00 horizont..
