The following diagram demonstrates an elastic collision between two balls of equal masses. The black ball is at rest and the final velocity v1 of the white ball = 3 m/s Find:

1. the initial velocity of the white ball,
2. the velocity of the black ball after the collision
3. the angle (theta)
4. the change in the kinetic energy

Is there a possibility we can discuss everything here? I'm having a hard time understanding. please help!

We should use the perfect inelastic collision equation

m1u1 + m2u2 = (m1+m2)v

can u post the diagram as well?

yep just a sec

anonymous · Answer

hii,
is the black bal at rest after the collision?
if yes then white ball's initial velocity is zero just before collision
