B and C assume that the collision of blocks m, and m2 is completely inelastic. (Because the spring is relaxedbefore the collision, block m3 does not move at the instant of impact. therefore (m, +m2) must move through a finitedisplacement before any force acts on m3 and cause it to move.)• For parts D and E assume that the collision of blocks m, and m, is elastic. (Because the spring is relaxed before thecollision. block mg does not move at the instant of impact. therefore m2 must move through a finite displacement before anyforce acts on mg and cause it to move.)B) After the collision, what is the minimum kinetic energy of block m, in units of joules?Answer:

1D Elastic Collision 1. You have two balls. They will collide elastically in 1D. Choose the following: • The masses of the balls (they cannot have the same mass). • The initial velocities of the balls (neither can be at rest). Solve for the final velocities of the balls after the collision using Conservation of Momentum and Conservation of Energy • Solve, you must draw a picture, set photo 1 and photo 2, and draw origin and axes?
