On February 15, 2013, a superbolide meteor (brighter than the Sun) entered Earth's atmosphere over Chelyabinsk, Russia, and exploded at an altitude of 25.75km. Eyewitnesses could feel the intense heat from the fireball, and the blast wave from the explosion blew out windows in buildings. The blast wave took approximately 5minutes 30 seconds to reach ground level. (a) What was the average velocity of the blast wave? b) Compare this with the speed of sound, which is 343 m/s at sea level.

On December 26, 2004, a great earthquake occurred off the coast of Sumatra and trig- gered immense waves (tsunami) that killed some 200, 000 people. Satellites observing these waves from space measured 800 km from one wave crest to the next and a period between waves of 1.0 hour. What was the speed of these waves in m/s and km/h? Does your answer help you understand why the waves caused such devastation?
Nuclear explosions cause a blast wave, a high-pressure shock wave generated by the heat from the fireball. These shock waves can travel in air at an average speed of 738 mph. (1 mile = 1609 meters). If a nuclear weapon in detonated in Pittsburgh, how far will the blast wave have traveled from the location of detonation 2.39 s after the explosion? (Give your answer in meters)

A bowling ball travelling with a constant velocity hits the pins at the end of a bowling lane (GIVEN A)m long. The bowler hears the ball hitting the pins (GIVEN B)s after the ball is released from his hands. What is the velocity of the ball? (speed of sound is 343 m/s)
Suppose you drop a rock into a dark well and, using precision equipment, you measure the time for the sound of a splash to return. (a) Neglecting the time required for sound to travel up the well, calculate the distance (in m) to the water if the sound returns in 2.1500 s. m (b) Now calculate the distance (in m) taking into account the time for sound to travel up the well. The speed of sound is 338.30 m/s in this well. m
