An astronaut of mass 65.0 kg is at rest relative to her space vehicle with nothing behind her except the empty, dark, vacuum of space. Another astronaut decides to play a practical joke on her and throws a 10.0 kg anvil (because those are totally used in space) at her with a velocity of 3.00 m/s. How fast do she and the anvil move once she catches it? Just to lower your anxiety, there is a way for her to get back to the space vehicle

A force of 10.12 N acts on a mass changing its momentum by 38.54 kg m/s. What is the time during which the force is in contact with the mass?
An astronaut floating at rest in space has run out of fuel in her jetpack. She realizes that throwing tools from her toolkit in the opposite direction will help propel her back toward the space station. If the astronaut has a mass of 85 kg and she throws a hammer of mass 4.5 kg at a speed of 4 m/s, what will be the approximate resultant velocity that carries her back to the space station?
A) A 2 kg mass with a speed of 0.5 m/s collides head on with a 1.5 kg mass moving with a speed of 0.3 m/s toward the first mass. What is the speed of both masses moving together after collision?
You are analyzing the possible defenses for an asteroid that is going to crash into Earth.Initially, the asteroid of mass ma is traveling to the left with speed vai . A missile of mass mm with initial velocity vmi to the right collides with the asteroid, and embeds itself inside the asteroid. Find the common final velocity of the missile and asteroid after the collision. ma = 1.3000E+9 kgmm = 9.1000E+7 kgvai x = -2200 m/svmi x = 12571 m/s [the final velocity for this one was -1233.67m/s] = vf x The missile then explodes, causing the asteroid to break into two chunks of mass m1 and m2. Solve algebraically for the final speeds of pieces 1 and 2 in terms of the masses of the two pieces (m1 and m2), the angles, the total mass before the explosion, and vf x (the velocity after the collision that you found above).Then use the following values for the parameters to get values for the speeds: m1 = 2.7820E+8 kgm2 = 1.1128E+9 kgθ1 = 30.2 degreesθ2 = 52.5 degrees This problem is dealing with…
