Question

For an experiement to test elastic collision, ball 2 was at rest and ball 1 was released from a certain height and distance and hit ball 2. A set of measurements were collected which was v1 and v2 prime for each ball. I need to calculate the kinetic energy before and after collision for both balls. Would I use the equation KE=1/2mv2 ?

Answer 1

yes

Answer 2

Im alittle confused because my data sheet gives values for mass, height, diameter and then v1 and v'2. So would v1 ball one and V'2 ball two?
