Question
Determine the Mach number of a car moving in standard air at a speed of(a) $25 \mathrm{mph}$(b) $55 \mathrm{mph},$ and(c) $100 \mathrm{mph}$
Step 1
We do this by multiplying the speed in mph by 0.447. For part (a), the speed of the car is 25 mph. So, we calculate the speed in m/s as follows: \[ V_{A} = 25 \times 0.447 = 11.175 \, m/s \] Show more…
