An airplane is traveling at 150 m/s in level flight. In order to make a change in direction, the airplane travels in a horizontal curved path. To fly in the curved path, the pilot banks the airplane at an angle such that the lift has a horizontal component that provides the horizontal radial acceleration to move in a horizontal circular path. If the airplane is banked at an angle of 12.0 degrees, then the radius of curvature of the curved path of the airplane is

Given Information:

Velocity = v = 150 m/s

angle = θ = 12°

Required Information:

Radius of curvature = R = ?

Radius of curvature =

Explanation:

Please refer to the attached diagram,

Where m is the mass of the plane and g is the gravitational acceleration.

Where v is the velocity of the plane and R is the radius of curvature of the curved path of the airplane.

Dividing eq. 2 by eq. 1 yields,

Therefore, the radius of curvature of the curved path of the airplane is 1.079×10⁴ m

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
