A fisherman notices that his boat is moving up and down periodically due to waves on the water. It takes a time of t = 2.8 s for the boat to travel from its highest point to its lowest, a total distance of d = 0.68m. The fisherman sees that the wave crests are spaced a horizontal distance of L = 6.10m apart. What is the velocity of the wave?

A fisherman 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 2.30 s for the boat to travel from its highest point to its lowest, a total distance of 0.620 m . The fisherman sees that the wave crests are spaced a horizontal distance of 5.90 m apart. How fast are the waves traveling? Express the speed v in meters per...

A composite string is made up of a short length of heavy string (µ1) and a very very long length of much lighter string (µ2 µ1). The light end of the string is attached to a pole very far away. The string is held under tension by passing the heavy end over a pulley and attaching it to a bag full of sand. The heavy segment of the string has length L (between the pulley and the knot between the...
