An airplane makes a gradual 90 turn while flying at a constant speed of 200 m/s. The process takes 20.0 seconds to complete. For this turn the magnitude of the average acceleration of the plane is

Respuesta :

Answer:

Explanation:

The plane travels a distance of 200 m/s(20.0 s) = 4000 m

A 90° turn is π/2 radians

4000 = (π/2)R

R = 8000/π m

a = v²/R = 200²/8000/π = 5π m/s² ≈ 15.7 m/s²
