E=0.5mv^2
That's the formula for kenetic energy. The only unknown we don't have is the velocity. In perticular the final velocity. To find this final velocity we need to use kinematic equations. Since we have the time and I'm also assuming that the initial velocity was zero we're going to use Vf=Vi+at. The acceleration is 9.8m/s^2 because its free fall and we have the time 22s. Vf= 9.8*22=215.6m/s
Now that we have the final velocity plug it in to the kenetic energy formula.
=0.5*3*215.6^2= 69725.04J
If you divide the circumference by its diameter, the constant ratio is called Pi, which is an irrational number shown with the symbol.
