1. The problem statement, all variables and given/known data http://imgur.com/FJzyuSY 2. Relevant equations 3. The attempt at a solution since the graph is velocity and time, i believe the slope SHOULD be distance or placement, correct? and 1 ball is dropped above the ground so I assume the answer is B since it has a line starting above the 0. and it makes sense since the slopes are curved because acceleration due to gravity will make the slopes curved, is this correct?
