An astronaut in her space suit has a total mass 94.5 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 18.0-kg oxygen tank away from her spacecraft with a speed of 4.00 m/s to propel herself back toward it. Determine the maximum distance in meters she can be from the craft and still return within 3.00 minutes.

Two manned satellites approaching one another at a relative speed of 0.100 m/s intend to dock. The first has a mass of 5.00 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. Assume that the positive direction is directed from the second satellite towards the first satellite.

What would an observer inside an elevator measure for the free‑fall acceleration ay near the surface of Earth if the elevator accelerates downward at 9.00 m/s2? Define the positive direction of motion as upward, away from Earth's surface. ay = ? m/s^2

while visitin a winery, you observe  wine shooting out of a hole at the bottom of a barrel.  The hole is .8 m below the top surface of wine.  Determine speed of wine leaving barrel's hole.  What would happen if there was a sealed lid on top of barrel? Why?

Two manned satellites approaching one another, at a relative speed of 0.200 m/s, intending to dock. The first has a mass of 5.00 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg.   a. Calculate the final velocity (after docking) in m/s by using the frame of reference in which the first satellite was originally at rest. (Assume the second satellite moves in the positive direction. Include the sign of the value in your answer.)  m/s   b. What is the loss of kinetic energy (in J) in this inelastic collision?  J   c. Repeat both parts by using the frame of reference in which the second satellite was originally at rest. final velocity (m/s) m/sloss of kinetic energy (J) J   Explain why the change in velocity is different in the two frames, whereas the change in kinetic energy is the same in both.

A spacecraft cruising in space at a constant velocity of 2000 ft/s has a mass of 25,000 lbm. To slow down the spacecraft, a solid fuel rocket is fired, and the combustion gases leave the rocket at a constant rate of 150 lbm/s at a velocity of 5000 ft/s in the same direction as the spacecraft for a period of 5 s. Assuming the mass of the spacecraft remains constant, determine (a) the deceleration of the spacecraft during this 5-s period, (b) the change of velocity of the spacecraft during this time period, and (c) the thrust exerted on the spacecraft.

An astronaut is doing a spacewalk on a long tether at 0.1 km away from the International Space Station (mass of 420,000 kg). His spacesuit includes a very sensitive gravitometer, which indicates the gravitational force acting on the astronaut and his spacesuit from the ISS is 7.0 E−7 N. What is the mass of the astronaut in his suit if G = 6.67 E−11 N*m2/kg2? 1. 150 kg 2.  200 kg 3. 250 kg 4. 300 kg

An astronaut with a mass of 75.8kg, finds herself 34.7m from her spaceship. The only way for her to return to the ship is to throw her 0.450kg wrench directly away from the ship. If she throws the wrench with a speed of 20.3m/s, how many seconds does it take her to reach the ship?

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. The first has a mass of 4.00 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg.
