An aeroplane has just landed icy asphalt and the needs to make a turn towards its parking spot. The coefficient of static friction 2 is half of what it is normally on this road when there is no ice. That is, 2= 0.51. If the tarmac were not icy, the plane could make the turn safely with a radius of curvature R1. What does the radius R2 need to be for the plane to make the same turn at the same speed given the icy conditions
