2. The simplest way to increase the size of a circular orbit is method called a HohmannTransfer (transfers the satellite from a small circular orbit to a larger one). It involvesfiring thrusters to create a change in velocity to get the satellite into a transfer orbit(elliptical), then later firing the thrusters again for another change in velocity to increasethe size of the orbit (back to circular). Diagram:bAvbTransferInitialFinalAvaaLet ussay we have the satellite from the previous problem in a circular orbit. We want toincrease the altitude of the circular orbit from 418 km to 1000 km. (a) Find the change invelocity necessary to go into the transfer orbit, Ava. (b) Find the change in velocitynecessary to go into the final circular orbit, Av. (c) How long will the transfer take?Constants needed:=G = 6.674 × 10-11 Nm²²/kg²Re = 6.378 x 106mMo5.974 x 1024 kg
