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