final (6) In an inelastic collision, the bodies collide and come apart again, but SOME KINETIC ENERGY IS LOST. That is, some kinetic energy is converted to some other form of energy. An example would be the collision between a baseball and a bat. If the bodies collide and stick together, the collision is called completely inelastic. In this case,

Elastic and Inelastic Collisions • A collision in which the objects stick together after collision is called a perfectly inelastic collision. – The objects do not bounce at all. – If we know the total momentum before the collision, we can calculate the final momentum and velocity of the now-joined objects. • For example:

where Ki is the total kinetic energy of the system before the collision and Kf is the total kinetic energy of the system afterthe collision. In a perfectly elastic collision, the fractional energy loss is equal to zero. Suppose we have two masses m2 and m1 that collide. Before the collision, m2 is initially at rest and m1 has velocity vi.

(a) Two objects of equal mass initially head directly toward one another at the same speed. (b) The objects stick together (a perfectly inelastic collision), and so their final velocity is zero. The internal kinetic energy of the system changes in any inelastic collision and is reduced to zero in this example. Find the recoil velocity of

We can find two unknowns because we have two independent equations—the equations describing the conservation of momentum in the x and y directions. 0 = m 1 v ′ 1 y+ m 2 v ′ 2 y . Therefore, v ′ 2 = 0.886 m/s. Note that the initial velocity of the goalie is zero and that the final velocity of the puck and goalie are the same.
