(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

An 80-kg pilot flies a plane in a vertical loop. At the top of the loop, where the plane is completely upside-down for an instant, the pilot hangs freely in the seat and does not push against the seat belt. The airspeed indicator reads the 110 m/s. What is the radius of the plane's vertical loop?

2. Relevant equations

F_{c}=F_{g}

F_{c}=mV^{2}/R

3. The attempt at a solution

So we know that m= 80kg v=110m/s and we are looking for R.

In order to do this, I simply rearranged the F_{c}=mV^{2}/R equation and solved for R. And this turned out to give me R=1 235m.

I would like if someone could verify that my work here is done correctly and that the significant figures are being respected. Thank you so much for your time and help :)
