A spacecraft can attain a stable orbit 300 kilometers above Earth if it reaches a velocity of 7.7 kilometers per second. The formula for a? rocket's maximum velocity v in kilometers per second is vequals=minus-0.0098+c ln R?, where t is the firing time in? seconds, c is the velocity of the exhaust in kilometers per? second, and R is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. Find the velocity of a spacecraft whose booster rocket has a mass ratio of 34?, an exhaust velocity of 2.7 ?km/s, and a firing time of 40s. Can the spacecraft achieve a stable orbit 300 km above? Earth? The maximum velocity of the spacecraft is approximately how many km/s
