See attached file for full problem description with units.
On a frictionless horizontal air table, puck A (with mass 0.369 ) is moving toward puck B (with mass 0.249 ), which is initially at rest. After the collision, puck A has velocity 0.116 to the left, and puck B has velocity 0.645 to the right.
a.) What was the speed of puck A before the collision?
Part B
Calculate , the change in the total kinetic energy of the system that occurs during the collision.
