Answer:
Speed of the plane will be equal to 2.969 m/sec
Explanation:
Note - It is not given but we have to find the speed of the plane.
We have given radius r = [tex]r=490mm=490\times 10^{-3}m[/tex]
Angular acceleration [tex]a=18m/sec^2[/tex]
We have to fond the speed of the plane
We know that angular acceleration is equal to [tex]a=\frac{v^2}{r}[/tex]
So [tex]18=\frac{v^2}{490\times 10^{-3}}[/tex]
[tex]v^2=8.82[/tex]
v = 2.969 m/sec
So speed of the plane will be equal to 2.969 m/sec
