The solution to the following real world problem:
A spacecraft can attain a stable orbit 300 km above Earth if it reaches a velocity of 7.7 km/s. Find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.7 km/s, and a firing time of 30s. Can the spacecraft achieve a stable orbit 300 km above Earth? Use v = -0.0098t + c ln(R)
What is 7.79 km/s. and yes it can achieve a stable orbit 300 km above Earth.
