Answer: Δt= 71.6 sec PROBLEMS(Unless otherwise indicated, the velocities mentioned inthe problems which follow are measured from a nonrotat-ing reference frame moving with the center of the attract-ing body. Also, aerodynamic drag is to be neglected unlessstated otherwise. Use g = 9.825 m/s² (32.23 ft/sec²) for theabsolute gravitational acceleration at the surface of theearth and treat the earth as a sphere of radius R = 6371 km(3959 mi).) 3/281 Just after launch from the earth, the space-shuttleorbiter is in the 37 × 137-mi orbit shown. The firsttime that the orbiter passes the apogee A, its twoorbital-maneuvering-system (OMS) engines arefired to circularize the orbit.
