21. ssm A two-stage rocket moves in space at a constant velocity of 4900 m/s. The two stages are then separated by a small explosive charge placed between them. Immediately after the explosion the velocity of the 1200-kg upper stage is 5700 m/s in the same direction as before the explo- sion. What is the velocity (magnitude and direction) of the 2400-kg lower stage after the explosion?

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 moveonce she catches it? Just to lower your anxiety, there is a way for her to get back to the space vehicle

Two masses undergo a front-to-back colli- sion. The masses are mi m, with initial velocity 2v0, and m₂ = 4m, with initial ve- locity vo. Due to the collision, they stick together, forming a compound system. 20 Vo G m₁ If m= 2.2 kg and vo= 3.9 m/s, find the magnitude of the loss in kinetic energy after the collision.

lease answer the following question(s): 1. Two manned satellites approach one another at a relative speed of 0.29 m/s, intending to dock. The first has a mass of 4.0x 10³ kg, and the second a mass of 7.5x10³ kg. If the two satellites collide elastically rather than dock, what is their final relative velocity? Final relative velocity = ✔m/s Submit Answer see other options - If you don't want to answer the question right now View Forum Activities (0 new of 0) Powered by CogBooks ▬▬ Search fs 10 Answering the question(s) helps us recommend your next activity. f6 99+

3. Two asteroids collide and stick together. The first asteroid has mass of 15 × 10³ kg and is initially moving at 770 m/s. The second asteroid has mass of 20 × 10³ kg and is moving at 1020 m/s. Their initial velocities made an angle of 20° with respect to each other. What is the final speed and direction with respect to the velocity of the first asteroid? How much thermal energy is generated in the collision?

A two-stage rocket moves in space at a constant velocity of +4570 m/s. The two stages are then separated by a small explosive charge placed between them. Immediately after the explosion the velocity of the 1060-kg upper stage is +5750 m/s. What is the velocity (magnitude and direction) of the 2250-kg lower stage immediately after the explosion?

Problem B) An inelastic collision occurs between a particle of mass 1.5 kg moving with an initial velocity of v = (-2i – 1.33 + 0.7k) m/s and another particle of mass 0.8 kg that has an initial velocity of v = (5.6å + 0.53 + 4.3k) m/s. What is the final velocity of the particles in unit vector notation? %3D

4. A 10-kg body is moving through space (ignore gravity) in the positive direction of a y axis with a speed of 140 m/s when, due to an internal explosion, it breaks into two pieces: piece A (mass = 2 kg) and piece B (mass = 8 kg). Piece A moves away from the point of the explosion with a speed of 50 m/s in the +x direction. Piece B has a velocity g after the explosion. a. What is the total linear momentum of the two-piece system after the explosion? Put your answer in unit vector notation. b. What is the x component and y component of the velocity VB of piece B after the explosion? Remember to include a plus or minus sign to indicate direction.
