An astronaut and equipment weigh 2,156 N on Earth. Weightless in space, the astronaut throws away a 5.4 kg wrench with a velocity of 5.5 m/s. What is the resulting velocity of the astronaut in the opposite direction? v = ______ m/s Please show all work.
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...
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....
An unfortunate astronaut loses his grip during a spacewalk and finds himself floating away from the space station, carrying only a rope and a bag of tools. First he tries to throw a rope to his fellow astronaut, but the rope is too short. In a last ditch effort, the astronaut throws his bag of tools in the direction of his motion, away from the space station. The astronaut has a mass of ma = 102 kg and the bag...
A deep-space vehicle moves away from the Earth with a speed of 0.760c. An astronaut on the vehicle measures a time interval of 2.55 s to rotate her body through 1.00 rev as she floats in the vehicle. What time interval is required for this rotation according to an observer on the Earth? s
An 80.0 kg astronaut who weighs 784 N on Earth would weigh how many Melons on the Moon?
Bonus/ Reminder: A 100 kg astronaut throws a 20 kg ball in outer space. During the throwing motion, the ball accelerated to the right at a rate of 2.5 m/s. What was the acceleration of the astronaut during this time?
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...
An astronaut out on a spacewalk to construct a new section of the International Space Station walks with a constant velocity of 1.50 m/s on a flat sheet of metal placed on a flat, frictionless, horizontal honeycomb surface linking the two parts of the station. The mass of the astronaut is 78.0 kg, and the mass of the sheet of metal is 250 kg. (Assume that the given velocity is relative to the flat sheet.) (a) What is the velocity...
An 97 kg spacewalking astronaut pushes off a 685 kg satellite, exerting a 97 N force for the 0.5 s it takes him to straighten his arms. a. What impulse is delivered to the astronaut from the satellite? kg m/s b. What's the speed of the astronaut after he pushes off? (We'll call the astronaut and satellites initial velocity 0.) m/s c. What's the speed of the satellite after the astronaut pushes off? m/s d. How far apart are the...
