A torpedo fired from a submerged submarine is propelled through the water
with a speed of 20.00 m/s and explodes upon impact with a target 2000.0 m
away. If the sound of the impact is heard 101.4 s after the torpedo was fired,
what is the speed of sound in water? (Because the torpedo is held at a constant
speed by its propeller, the effect of water resistance can be neglected.)
