[15 second video and three questions] Inelastic collisions.

Youtube Link: https://www.youtube.com/watch?v=cVjxn4KjOb4

Why is the collision inelastic and not elastic?

When a bullet is fired into a ballistic, where is the kinetic energy lost?

If the bullet that is fired at the ballistic pendulum exits the block, is the collision elastic or inelastic? Would you still be able to determine the initial velocity of the bullet?

Doesn't have to be overly thorough, just help me make sense of it.

Thank you :)

Explanation / Answer

a) The bullets get embeded into the wooden piece hanging so the collision is inelastic.

b) The loss in kinetic energy in the collision system would be in the form of heat on the wooden block & bullet. The deformation in the shape of wooden and bullet is dueo the loss in kinetic energy

c) If the bullet comes out the block then the collision is elastic. Regardless of type of collision, momentum is conserved, this mean that we can determine the speed of the of bullet by taking the height of rise of the block.
