Chapter 2, Problem 51PE

Standing at the base of one of the cliffs of Mt. Arapiles in Victoria, Australia, a hiker hears a rock break loose from a height of 105 m. He can't see the rock right away but then does, 1.50 s later. (a) How far above the hiker is the rock when he can see it? (b) How much time does he have to move before the rock hits his head?

A supersonic jet flying at 20 m/s is accelerated uniformly at a rate of 23.1 m/s² for 19 seconds. (a) What is the jet's final velocity? (b) The speed of sound is 331 m/s in air. How many times the speed of sound is the jets final speed? A new type of gun is being developed by engineers. The gun will be used to launch a rocket as if they were bullets. One of the guns can give a small object a velocity of 5 km/s moving it through only 10 cm. a. What acceleration does the gun give this object? meidong a b. Over what time interval does the acceleration take place?
A stone is dropped (from rest) into a deep well. The splash in the water below is heard 4.2 seconds after it is released (when it starts falling from the top of the well). What is the depth of the well? Ignore air resistance and assume the speed of sound is 343m/s
A "rock" is dropped from the top of a cliff of unknown height. The sound of the impact below is heard 2.7 seconds after its release. Speed of sound is 340 m/s. What's the height of the cliff?
