v=-0.0098t + c In R v is the velocity of a rocket, t is the firing time, c is velocity of the exhaust, 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 to the nearest hundredth 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.
