1. The problem statement, all variables and given/known data 3. The attempt at a solution I used conservation of momentum for the initial velocity of mass 2, and conservation of mechanical energy for the movement from rest to highest position, KE=PE. The answer that I received is selected in the screenshot. However, when the calculations were completed, I received a value of 1.81m... Which is longer than the string. Does anyone spot my problem? Thank you.
