Review Constants Periodic Table Part A A 75-kg astronaut (including spacesuit and equipment) is floating at rest a distance of 15 m from the spaceship when she runs out of oxygen and fuel to power her back to the spaceship. She removes her oxygen tank (3.0 kg) and flings it away from the ship at a speed of 15 m/s relative to the ship. At what speed relative to the ship does she recoil toward the spaceship? Express your answer...

an astronaut is at rest in space outsider of her spaceship. using her jetpack, she tries to propel herself back to the ship but realizes her jetpack is out of fuel. instead, she decides to throw the jetpack away from the ship, hoping it would move her towards the ship. if she throws the jetpack away from the ship at a speed of 6m/s, what speed will the astronaut have back towards the ship? astronaut mass: 80kg, jetpack mass: 40kg

A 61kg astronaut (including spacesuit and equipment), is floating at rest a distance of 10 m from the spaceship when she runs out of oxygen and fuel to power her back to the spaceship. She removes her oxygen tank (3.0 kg) and flings it away from the ship at a speed of 15 m/s relative to the ship. PART A: At what speed relative to the ship does she recoil toward the spaceship? My attempt: m1V1=m2V2 (3kg)(15m/s) = (61kg)(V2) 45...

Suppose you are an astronaut on a spacewalk, far from any source of gravity. You find yourself floating alongside your spacecraft but 10 m away, with no propulsion system to get back to it. In your tool belt you have a hammer, a wrench, and a roll of duct tape. How can you get back to your spacecraft? a. Move like you are flying to the spaceship b. Move like you are swimming to the spaceship c. Throw the items...

Jenna Parson is a long-term client in your ambulatory care medical center who suffers from severe headaches and debilitating back pain after serving in Afghanistan. You have reason to believe she is abusing her pain medications. Your chart notes indicate that either she or her pharmacy calls for refills on her prescription prior to the time when she should be out of her medications. You have two notes, one indicating she accidentally spilled most of her pills down the sink,...

An astronaut in her space suit has a total mass of m, = 90.0 kg, including suit and oxygen tank. Her tether line loses its attachment to her spacecraft while she's on a spacewalk. Initially at rest with respect to her spacecraft, she throws her oxygen tank of mass m, - 12.0 kg away from her spacecraft with a speed v = 7.50 m/s to propel herself back toward it (see figure). (a) Determine the maximum distance she can be...
