What vertical distance δy does a free-falling particle travel from the moment it starts to the moment it reaches a speed of 7.9 m/s if it starts from rest? work out your solution using one of the equations for vertical motion with constant acceleration, specifically, v2f=v2i+2aδy, where vi and vf are the particle’s initial and final speeds, respectively, and a is the particle’s acceleration.
