**Airplane Free-body diagram!**

## Homework Statement

A plane with mass of

**1090 kg**is flying straight and level at an altitude of 1100 meters & a constant velocity of

**200 kg/hr**

*(55.55m/sec).*Assuming that the acceleration due to gravity is

**10 m/sec^2**, the force on the plane due to gravity is

**10900 Newtons**. Since the plane is in level flight, the net force in the y direction is 0 & the lifting force provided by the wings equals the weight of the plane. The piolot now banks the wings at a

**7.5 degree**angle w/ respect to the vertical in order to make a turn. Part of the lifting force of the wings is now used to make the plane turn in a circle & there's less lift to counteract the force of gravity.

How long will it take the plane to make one turn of

**360 degrees**at a velocity of 200 km/hr (55.55 m/sec)??

## Homework Equations

Vf=Vo+aT

S=Vo(T)+1/2(a)(T)^2

s=theta(r)

Time=Distance/radius

## The Attempt at a Solution

**NO CLUE!**HELP!

All I know is that the value that the lift should be increased so that the plane doesn't decend is

**10994 Newtons**and that the

**radius**of the circle that the plane will fly w/o loosing altitude w/ constant velocity of 200km/hr is

**2343 m.**
