# Circular motion

A plane heading due North makes a level turn with a speed of 100 m/s. The angle of the bank is 15 degrees. Determine:

(a) Radius of the circular path

(b) Cetripetal acceleration

(c) Lift force

(d) Direction of velocity after 30 seconds (Weight of the plane is 19600 Newtons)

#### Solution Preview

Let the lift be L which acts perpendicular to the plane's wings

mg= 19600 N

m= 1997.96 kg as g=9.81 m/s

v= 100 m/s

L Cos 15 ...

#### Solution Summary

This solution calculates radius of the circular path, cetripetal acceleration, lift force and direction of velocity after 30 seconds.
