Suppose the space shuttle is in orbit 430 km from the Earth's surface, and circles the Earth about once every 93.2 minutes. Find the centripetal acceleration of the space shuttle in its orbit. Express your answer in terms of g, the gravitational acceleration at the Earth's surface.

centrip acceleration=w^2 r
where w=2PI/periodinseconds
r is re+altitude
