An astronaut of mass 210 kg including his suit and jet pack wants to acquire a velocity of 2.0 m/s to move back toward his space shuttle. Assuming the jet pack can eject gas with a velocity of 35 m/s, what mass of gas I will need to be ejected? 0 = mu₁' + M₂U₂' M₂ = -M,U₁' V2' =- -(210kg 20uls)=-12kg 350Ats

An astronaut of mass 210 kg including his suit and jet pack wants to acquire a velocity of 2.0 m/s to
move back toward his space shuttle. Assuming the jet pack can eject gas with a velocity of 35 m/s, what
mass of gas will need to be ejected?
Mr. de Jong
O 0 =
M₁U₁' + M2U ₂'
- M₁U,'
V₂'
M₂' = -
