During the boost phase of the Atlas V, the RD-180 engine operates together with three solid propellant rocket motors (SRBs) for the initial stage. For the remaining thrust time. the RD-180 operates alone. Using the information given in Table 1-3, calculate the overall effective exhaust velocity for the vehicle during the initial combined thrust operation.
