Assuming that the speed of sound at a certain altitude is 330m/s calculate the speed of an airplane that is travelling at
(A) mach 0.70
What is .7*330m/s ?
To calculate the speed of an airplane traveling at a certain mach number, we need to use the following formula:
V = Mach * Speed of Sound
First, we need to convert Mach 0.70 into a decimal by dividing it by 100:
Mach 0.70 = 0.70 / 100 = 0.007
Next, we can substitute the values into the formula:
V = 0.007 * 330
Now, we can calculate the speed of the airplane:
V = 2.31 m/s
Therefore, an airplane traveling at Mach 0.70 would have a speed of approximately 2.31 m/s at the given altitude, where the speed of sound is 330 m/s.
