Question

# A space shuttle showed in the figure below has orbiter with three main engines, two solid rocket boosters and an external tank. The external tank to which the boosters and

orbiter are attached to,supplies fuel to the main engines of the orbiter. Lift-off mass of the space shuttle is 2.03 * 10°kg. Each solid rocket booster creates a thrust of 12.5 * 10°N Each of the three main engines has thrust of1.75 * 10°N. Assume gravitational acceleration.210m/s and constant acceleration of the space shuttle throughout the flight. Now answer the following questions: When the main three engines are running, and the solid rocket boosters are off, will there be lift off? When all main three engines and two solid rocket boosters are running together, calculate the acceleration at which there will be lift off. When all main three engines and two solid rocket boosters are running together, calculate the acceleration at which there will be lift off. For the Space Shuttle, the solid rocket boosters(SRBS) have enough propellant to provide thrust for2 minutes and 4 second, after that they separates.By this time at what altitude it'll reach and whatwould be its velocity? After SBR separation, fuel continues to be pumped to the three main engines for another 6 minutes thus maintaining the same acceleration. At this point at what altitude the space shuttle will reach and what would be its velocity?
