1. The problem statement, all variables and given/known data It takes 2.70 s for a small ball with a mass of 0.050 kg released from rest from a tall building to reach the ground. Calculate the height from which the ball is released. 2. Relevant equations F=MA Vo=h/t - .5at 3. The attempt at a solution I plugged in all the knowns into the above equation but was still left with an unknown initial V and an unknown height. unsure how to proceed.
