I know I need the equations for 1) period and 2) centripetal acceleration and 3) r.

1) T= (2pi x r)/v (seconds)

2) a= v^2/r (m/s^2)

3) 589 km

I converted T=92.26 min into seconds and got 5775.6s and converted 589km to meters. I then plugged these numbers into equation 1 to solve for velocity (v= (2pi x r)/T). I used this velocity as well as 589,000m for r to find acceleration using equation 2.

The answers I calculated for both velocity and acceleration are wrong, and I think my problem lies in my value for r.

Did I interpret this incorrectly? Any input on what r should be (or if I made another mistake) is greatly appreciated! Thank you!
