Calculate Plane Speed from Diameter & Angle

[courtney1121]

A plane is traveling in a circular path 32 km in diameter. It is banking at an angle of 12o, which indicates that its sideward acceleration is 2.1m/s2. What is its speed?


So I can use v=at, but I don't know time. What am I suppose to do with the 32km and the angle of 12?

ok so how does the banking angle indicate the sideward acceleration?

 

[courtney1121]

is it possible to use the equation v^2 = a * radius * tan angle?

From using that equation I got speed to be 84.5m/s...does that sound right?
