Bores Under certain conditions, tsunami waves encountering land will develop into bores. A bore is a surge of water much like what would be expected if a dam failed suddenly and emptied a reservoir in to a river bed. In the case of a bore travelling from the ocean into a dry river bed, one study shows that the velocity
where
a. A bore travels up a dry river bed. How does the velocity of the tip compare with its initial velocity when its height is reduced to half of its initial height?
b. How does the height of the bore compare with its initial height when the velocity of the tip is reduced to half of its initial velocity?
c. If the tip of one bore surging up a dry river bed is three times the height of another, how do their velocities compare?

- YOUR TURN A 25ft ladder is placed against a building. The base of the ladder is slipping away from the building at a rate of 3ftperminute. Find the rate at which the top of the ladder is sliding down the building when the bottom of the ladder is 7ft from the base of the building.arrow_forwardFrictional Force The frictional force F between the tires and the road required to keep a car on a curved section of a highway is directly proportional to the square of the speed s of the car. If the speed of the car is doubled, the force will change by what factor?arrow_forward
