2. An 80 kg astronaut is on a spacewalk away from the shuttle when his tether line breaks. Starting at rest (relative to the shuttle) he throws the 9.5kg oxygen tank away from him with a velocity of -2.0 m/s so that he recoils in the opposite direction, towards the shuttle. BEFORE AFTER V=VA=0 m=10 mA=80 V=2 m=9.5 VA'=? mA=80 a. Write the momentum conservation equation for this system in terms of variables (m, v). b. Find the speed with which the astronaut moves towards the shuttle. Pbefore = Pafter
