1. Homework Statement
If the temperature is 12 degrees and a jet accelerates at rest at 12ms2 for 41s, then what is the Mach value for the jet at the end of 41 seconds


2. Homework Equations
mach#=vovs
speed of sound equation

3. The Attempt at a Solution

v=12degrees
a=12ms2
v=339,08ms
m#=vo/vs

Your statement of the problem has numerous flaws. I assume the jet accelerates from rest, and that you meant "t=12degrees" above. Careful also to use acceleration units of meters per second^2, not m-s^2. Finally your value for v is incorrect.

What is the equation giving velocity in terms of acceleration and time? Once you have that you'll need the speed of sound at 12 degrees to finish the problem...
