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

An astronaut in her space suit has a total mass of 87.0 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 12.0-kg oxygen tank away from her spacecraft with a speed of 8.00 m/s to propel herself back toward it, as shown in Figure 1. Determine (a) her speed after throwing the oxygen tank away and (b) the...

A 65kg astronaut (including spacesuit and equipment), is floating at rest a distance of 15m 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? How long must she hold her breath before reaching the ship?

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...

An astronaut is taking a space walk near the shuttle when her safety tether breaks. The astronaut takes a tool from her tool belt and throws it away from the shuttle to get back to the shuttle. If the astronaut throws the tool with a force of 16.0 N, what is the magnitude of the acceleration a of the astronaut during the throw? Assume that the total mass of the astronaut after she throws the tool is 80.0 kg. Answer...

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...

While on an interplanetary mission, a 58.5-kg astronaut is floating toward the front of her ship at 0.15 m/s, relative to the ship. She wishes to stop moving, relative to the ship. She decides to throw away the 2.50-kg book she's carrying. What should the approximate speed and direction of the book be to achieve her goal?

An astronaut is performing EVA (extra-vehicular activity - this is NASA-speak for a space walk) near the International Space Station (ISS) when her jet pack malfunctions. There are two objects within her reach that she can use to propel herself back to the safety of the ISS. Object A has her mass M, and object B has a mass of 10 middot M (ten times greater). Which object should she push on to achieve a given momentum towards the ISS...

1 If a 71-kg astronaut at rest in space throws a ball with mass 0.61 kg at a speed of 12 mph. What happens to the astronaut as a result? 4 A moving ball collides elastically with another ball that is twice as heavy and is initially at rest. What happens to the lighter ball as a result of the collision? (a) She picks up some of the movement of the ball, causing her to move forward....
