1. The problem statement, all variables and given/known data A body of mass 50 kg is allowed to fall freely under the action of gravity. Calculate the momentum it possesses after 5 seconds 2. Relevant equations P=mv F=ma 3. The attempt at a solution I'm thinking we're really looking for how force affects momentum here? Since (F=ma) and acceleration is just how velocity changes over time would we use: F = m * v/t and then replace v with a = F=(50)(9.81)/5 = 98.10 J Is this correct?
