Question

*A ball of mass 6.5 kg moving with a speed of 15 ?m/s to the right collides head-on with a 3.5 kg ball ?which is at rest. If the collision is elastic, what is ?the speed and direction of each ball after the ?collision?

Answer 1

I found a similar problem to show you how to do it and the equations you are supposed to use. So in this case, you have to solve for v1 and v2 separately because it is elastic

Answer 2

Notice that this is not your problem but it is the same thing with different numbers
