Question

plane is circling the airport. It takes 35 min to do one circle with a radius of 5.0 x 10^4 m. The plane weighs 6.05 x 10^4 kg. What the angular velocity

Answer 1

I think this question has a lot of extra information. If I'm not mistaken, the only thing you should need to calculate angular velocity is the time it takes the moving object to traverse a circle once.
I guess we could put the velocity in units of (angle/radian) per minute?
So, if it takes 35 minutes for the plane to do a full circle, which is 360 degrees, how many degrees of the circle does the plane cover in 1 minute?
You may have to convert the angle to radians, but this is essentially how you calculate angular velocity.
