23. Two balls, each with a mass of 2 kg, and velocities of 2 m/s and 3 m/s collide head on. Their final velocities are 3 m/s and 2 m/s respectively. Is this collision elastic or
inelastic? Explain. (use the lab to help answer this question

In an "elastic" head on collision the objects will exchange velocities:

The collision was elastic - Also energy in = energy out for an elastic collision.

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
