a 5.00g object moving to the right at 20.0cm/s makes an elastic head-on collision with a 10.0g object that is initially at rest. Find the velocity of each object after the collision.
The Attempt at a Solution
I have attempted this question several times.
I have converted all units to kg and m/s before starting all calculations.
I found the momentum for each using p=mv but this was not the right answer.
then I tried the other equation I have given and tried to minus the initial velocity from answer - still its not correct.
I am not great at collisions and find these really difficult - esp the conservation of energy/momentum concepts. I don't know to translate the conceptual into the application using equations and the info given in the question.
Please someone help me.
