1. The problem statement, all variables and given/known How long does a 1kg ball to reach the momentum of 75.5kgm/s if it free falls? 2. Relevant equations Momentum= mass x velocity F = (m x change in velocity) / change in time 3. The attempt at a solution I used the first formula to find the velocity, which is 75.5m/s but I'm not sure what to do next.
