A car traveling with an initial velocity of 10 m/s accelerates at a constant rate of 2.2 m/s2 for 2 seconds.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?
