1. The problem statement, all variables and given/known data A boy throws a baseball directly upward. He catches it 3.2 seconds later. 2. Relevant equations a=Δv/Δt 3. The attempt at a solution Letting up be positive, I think the acceleration would be positive 9.8 m/s^2. I think I am trying to find the final velocity. I think that the inital velocity would be 0, right before he throws the ball. Could I go about this problem by using a=Δv/Δt to find velocity? This method seems to yield an answer of 3.0625 m/s. Thanks in advance for a helpful reply!
