A 121-kg astronaut (including space suit) acquires a speed of 2.30 m/s by pushing off with her legs from a 1800-kg space capsule. Use the reference frame in which the capsule is at rest before the push.

Part A

What is the velocity of the space capsule after the push in the reference frame?

Part B

If the push lasts 0.680 s , what is the magnitude of the average force exerted by each on the other?

Part C

What is the kinetic energy of the astronaut after the push in the reference frame?

Part D

What is the kinetic energy of the capsule after the push in the reference frame?

    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...

    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 in his space suit and with a propulsion unit (empty of its gas propellant) strapped to his back has a mass of 146 kg. The astronaut begins a space walk at rest, with a completely filled propulsion unit. During the space walk, the unit ejects some gas with a velocity of 32 m/s. as a result, the astronaut recoils with a velocity of .39 m/s. After the gas is ejected, the mass of the astronaut (now wearing a...

    An astronaut of mass 60 kg is on a space walk to repair a communications satellite when he realizes he needs to consult the repair manual. You happen to have it with you, so you throw it to him with a speed 4 m/s relative to the spacecraft. He is at rest relative to the spacecraft before catching the 3 kg book. Find (a) his velocity after catching the book (b) the initial and final kinetic energies of the book-astronaut...

    answer all please 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....
