The speed of sound in air at room temperature is about s=343 m/s. calculate this speed in miles per hour (mph). (1 mi = 1609 m.)
igor_vitrenko [27]
Given:
1 mi = 1609 m.

Also,
1 hour = 3600 s

Therefore
343 \,  \frac{m}{s} =(343 \,  \frac{m}{s} )*(3600 \,  \frac{s}{h}) *( \frac{1}{1609}\, \frac{mi}{m})=  767.433 \,  \frac{mi}{h}

Answer: 767.4 mph (nearest tenth)

vredina [299]
Given:
u = 10⁵ m/s, the entrance velocity
v = 2.5 x 10⁶ m/s, the exit velocity
s = 1.6 cm = 0.016 m, distance traveled

Let a = the acceleration.
Then
u² + 2as = v²
(10⁵ m/s)² + 2*(a m/s²)*(0.016 m) = (2.5 x 10⁶ m/s)²
0.032a = 6.25 x 10¹² - 10¹⁰ = 6.24 x 10¹²
a = 1.95 x 10¹⁴ m/s²

Answer: 1.95 x 10¹⁴ m/s²
