## NotTim Group Title An 82 Kg pilot is flying a stunt airplane pulls out of a dive at a constant speed of 540 km/h. What force is applied on the pilot by the plane seat at the lowest point in the pullout? one year ago one year ago

So what is the formula for centripetal force?

4. NotTim Group Title

Fc=mv^2/r

5. wio Group Title

And since he is at the bottom of the circle, the centripetal force is in the same direction as the force of gravity. So they are both just added, right?

6. wio Group Title

So $$\Large F_{net} = m\frac{v^2}{r}+ma_{gravity}$$ We have $$m, v, r, a_{gravity}$$ right? So does this get you the correct answer?

7. NotTim Group Title

lemme try this one out first. thx for the help and immediate response

8. NotTim Group Title

is gravity suppose to be negative?
