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

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…

You and another astronaut are in space.  You throw a tool to them that has a mass of 15kg.  Your mass is 91kg and the other astronaut's mass is 88kg. Initially you and the other astronaut are at rest.  You threw the tool at a speed of 8m/s.  What is your velocity after you threw the tool?

A toy train engine (3.4 kg) is moving 0.25_m/s to the right when it collides with a train car (3.9.kg) moving 0.15 m/s in the opposite direction, and they stick together. Find the velocity of the engine-car combination as they move off together. Assume "to the right" is the positive direction. 0.04319_m/s В. 0.05252_m/s 0.0687_m/s 0.04904 m/s 0.03505_m/s F. А. D. Е.

Bob and Tom take a sled weighing 10 N to a frozen pond. The sled is initially at rest on the ice. Bob who weighs 490 N runs at 2 metres per second and jumps on the sled. A few seconds later, Tom who weighs 540N runs at 4 metres per second and jumps on the sled with Bob. Keep all values to 3 decimal places. A)What is the velocity of the sled after Bob jumps on to it? B)What is the velocity of the sled after Tom jumps on it?

A rigid ball of mass m and velocity u undergoes an inelastic collision with another rigid ball of mass m and velocity -u. After the collision, the balls stick together. Find the mass of the composite object after the collision. What must |u| be for the composite object mass to be 3m?

A mass of m1= 4 kg moving with a velocity of v1=(2 m/s)ˆi (positive x−direction) collides with another mass, m2 moving at v2= (−4 m/s)ˆi (negative x−direction). The masses collide and stick together, moving off with a velocity of v= (−2 m/s)ˆi. What is m2? A)m2= 4 kg B)m2= 8 kg C)m2= 12 kg D)m2= 16 kg
