A 95-kg astronaut and a 1300-kg satellite are at rest relative to the space shuttle. The astronaut pushes on the satellite, giving it a speed of 0.17 m/s directly away from the shuttle. Seven-and-a-half seconds later the astronaut comes into contact with the shuttle. What was the initial distance from the shuttle to the astronaut?

What speed does this give Ann as she moves toward the shuttle
Ann the Astronaut weighs 60 kg. She is space walking outside the space shuttle and pushes a 350-kg satellite away from the shuttle at 0.90 m/s. What speed does this give Ann as she moves toward the shuttle?

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...

a 63.0 kg astronaut is on a spacewalk when the tether line to the shuttle breaks. The astronaut is able to throw a spare 10.0 kg oxygen tank in a direction away fromthe shuttle with a speed of 12.0 m/s, propelling the astrounaut back to the shuttle. Assuming that the astrounaut starts from rest with respect to the shuttle, findthe astronaut's final speed with respect to the shuttle after the tank is thrown

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....

A 60.0 kg astronaut is in outer space far from any object that would exert a significant gravitational force on him. He is outside of his spaceship and, initially, is stationary with respect to it. He would like to move toward his spaceship, but his jet pack is not functioning. To start his journey to safety, he pushes a 2.00 kg mallet with a speed of 5.0 m/s in the direction away from the ship. What is the astronauts speed...

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 1740-kg communications satellite is released from a space shuttle to initially orbit the Earth at a radius of 9. 106 m. After being deployed, the satellite's rockets are fired to put it into a higher altitude orbit of radius 4. 107 m. What is the minimum mechanical energy supplied by the rockets to effect this change in orbit?

An astronaut of mass 84.0 kg is taking a space walk to work on the International Space Station. Because of a malfunction with the booster rockets on his spacesuit, he finds himself drifting away from the station with a constant speed of 0.690 m/s. With the booster rockets no longer working, the only way for him to return to the station is to throw the 8.95 kg wrench he is holding. In which direction should he throw the wrench? away...

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?
