- Sandra Bullock Is Doing A Spacewalk And Making Some Repairs On A Spacecraft While George Clooney Watches Anxiously Sudd 1 (97.93 KiB) Viewed 41 times
Sandra Bullock is doing a spacewalk and making some repairs on a spacecraft while George Clooney watches anxiously. Suddenly, her tether mysteriously snaps, and she is drifting away from the spacecraft at 0.537 m/s! a) (3 pts) What is the total momentum of Sandra and her heavy-duty wrench at this point, if she has a mass of 152 kg (including spacesuit) and the wrench has a mass of 3.35 kg? b) (3 pts) Thinking quickly, Sandra twists her body so that she is facing away from the spacecraft, and throws her heavy-duty wrench away from her and the ship. The wrench heads away at 29.5 m/s. Explain why momentum is conserved in this case. c) (4 pts) Calculate the size and direction of Sandra's velocity after he throws the wrench. Can she be saved?
