19. which type of collision is hitting a baseball with a bat? * 2 points elastic collision inelastic collision neither both

The answer is partially inelastic collision

In this type of collision there is no conservation of kinetic energy, and the objects don't stick together after the impact.

There is deformation of the ball (which causes heating)

There is friction between the ball and the bat.

And there is loss of energy due to sound. 

Iam on that question know can you tell me the answer i am realy strruglingasap
