An airplane is doing a vertical loop in the air. The airplane goes at a velocity of 320 and at the top of the loop, n=500N. The pilot weighs 62kg.

calc the radius of the loop

vertical loop, given: v=320, n at the top=510N, m=62kg

i don't know what eqn i use to find the radius of the loop..

What is n?

You will be using centripetal force=weight of plane and pilot

v^2/r= g
Normally, if at the top centforce exactly equals weight.
but I don't know what you mean by n.

To find the radius of the loop, we can use the centripetal force equation:

Fc = m * (v^2 / r)

Where:
- Fc is the centripetal force (equal to the normal force at the top of the loop),
- m is the mass of the pilot,
- v is the velocity of the airplane,
- r is the radius of the loop.

In this case, the centripetal force at the top of the loop is equal to the normal force:

Fc = n = 500N

Plugging in the given values:

500N = 62kg * (320^2 / r)

Now we can solve this equation to find the radius of the loop.

Rearranging the equation:

r = 62kg * (320^2 / 500N)

Calculating:

r = 62kg * (102,400 / 500N)

r ≈ 12,704 meters

Therefore, the radius of the loop is approximately 12,704 meters.
