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 ?

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?
To calculate the kinetic energy before and after the collision for both balls, you will need to use the equation KE = 1/2 * m * v^2. Here, KE represents the kinetic energy, m represents the mass of the ball, and v represents the velocity of the ball.
In your case, you have values for mass, height, diameter, and velocities v1 and v2 prime. The velocity before the collision is represented by v1, and the velocity after the collision is represented by v2 prime.
To calculate the kinetic energy before the collision (KE1), you would substitute the given values of mass and velocity (v1) for ball 1 into the equation KE = 1/2 * m * v^2.
Similarly, to calculate the kinetic energy after the collision (KE2), you would substitute the given values of mass and velocity (v2 prime) for ball 2 into the same equation.
Remember to square the velocity in the equation to get an accurate result.
Let's go step by step:
1. Calculate the kinetic energy before the collision for ball 1 (KE1):
KE1 = 1/2 * m1 * v1^2
2. Calculate the kinetic energy after the collision for ball 2 (KE2):
KE2 = 1/2 * m2 * (v2 prime)^2
Make sure to use the appropriate mass and velocity values for each ball in the equations.
By substituting the given values into the equation, you will be able to calculate the kinetic energy before and after the collision for both balls.
