Two 2.3 kg bodies, A and B, collide. The velocities before the collision are v → A = ( 34 i ̂ + 29 j ̂ ) m/s and v → B = ( 19 i ̂ + 1.6 j ̂ ) m/s . After the collision, v → A ′ = ( 4.0 i ̂ + 12 j ̂ ) m/s . What are (a) the x-component and (b) the y-component of the final velocity of B? (c) What is the change in the total kinetic energy (including sign)?

Given the mass of two blocks that collide, and the velocities of each block before and after the collision, be able to determine whether the collision was elastic, partially or completely inelastic, or not possible since an unnamed external force would be necessary to change the momentum, and/or kinetic energy of the system. Please explain in simplest terms and give an example using units given.

Two asteroids collide in space. The collision is not completely inelastic--the asteroids pull apart and continue on their way. Their masses are 8.7 X 108 kg for Asteroid A and 3.4 X 108 kg for Asteroid B. Treat Asteroid A as being initially at rest. Asteroid B, moving at high speed, strikes Asteroid A and moves from the collision at a speed of 7300 m/s in a direction 48 degrees from its original path. Meanwhile, Asteroid A moves away from...
