# Circular motion

Not what you're looking for?

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 Summary

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

##### 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 ...
