A 4400 kg rocket is set for vertical firing. If the exhaust speed is 1500 m/s, at what rate (in kilograms/second) must the gas be ejected to supply the thrust needed to give the rocket an initial upward acceleration of 23.0 m/s^2?

Not sure where to start.

  • Physics (Energy and Momentum) - ,

    solved using thrust = v (dM/dt)

  • Physics (Energy and Momentum) - ,

    You are given V and are solving for dM/dt what do you set it equal to?
