A stunt pilot who has been diving vertically at 150m/s pulls out to dive into a circle in the vertical plane.(adsbygoogle = window.adsbygoogle || []).push({});

a)What is the minimum radius of the circle, if the force on the pilot is not to exceed 6g.

b)If the pilot has a mass of 80kg, what is the apparent weight of the pilot at the lowest point of the circle?

My solution:

a)6g = mv^2/r

r= 383*mass metres

b) 6g = R-mg

R= g(6+80)

=844N

Is the above correct? The answer to part a) seems abit too large to me!

Thank you very much for any assistance, I really appreciate it.
