1. The problem statement, all variables and given/known data This figure shows two identical billiard balls before and after a glancing collision. Determine the speed of the other ball. 2. Relevant equations 0=mv1sin30- mv2sin60 3. The attempt at a solution v1= [(0.05m/s)sin60]/(sin(30))= 0.087 m/s Here I am looking for someone to check my calculations and that I have respected the proper number of significant figures. I was also wondering if anyone could explain to me what the difference is between an elastic collision and a glancing collision? Thanks so much in advance!
