The space shuttle, together with its central fuel tank and two booster rockets, has a total mass

Question:

The space shuttle, together with its central fuel tank and two booster rockets, has a total mass of 2.04(106) kg at liftoff. Each of the two booster rockets produces a thrust of 11.80(106) N, and each of the three main engines of the shuttle produces a thrust of 2.00(106) N. The specific impulse (ratio of exhaust velocity to gravitational acceleration) for each of the three main engines of the shuttle is 455 s. Calculate the initial vertical acceleration a of the assembly with all five engines operating and find the rate at which fuel is being consumed by each of the shuttle’s three engines.
