The rocket seen in the figure is initially at rest and contains pressurized air at 20C and 20 bars (kept constant). Rocket and the pressurized air inside weigh M1 and M2 respectively. At t=0 nozzle opens and the air jets out adiabatically and invicidly from the nozzle. Drive an expression for the time dependent velocity of the rocket as function of d, M1 and M2. Assume no air drag due to rocket motion. HINT: X ax + b dx b In\ax + b| X = a 20bars pa air P atm
