A physicist at a fireworks display times the lag between seeing an explosion and hearing its sound. She finds it to be 0.36 s.

a) How far away is the explosion, in meters, if the air temperature is 18°C (with a velocity constant of v = 331 m/s) and if you neglect the time taken for light to reach the physicist?

b) Calculate the distance, in meters, to the explosion taking the speed of light into account. (Note that this distance is negligibly greater than what you found in part (a).)

I understand the equation to be used is v = vo (sqrt( T/273)) but how was this equation derived?

Expert Solution

The answers are in the images. Page number is mentioned at right top. As you have asked, I have derived the equation v = v₀(sqrt(T/273)) at 1st.

During a fireworks display, a 0.300-kg bottle rocket approaches the top of its trajectory and explodes into two pieces as in the figure. The first piece (Piece 1) has mass 0.200 kg and the second piece (Piece 2) has mass 0.100 kg. Immediately after the explosion, the first piece is observed traveling to the left at a speed of 4.20 m/s and the second piece is observed traveling at an angle θ = 32.0° above the horizon at a speed...
