1. The problem statement, all variables and given/known data A student throws a stone vertically downward with an initial velocity of 5.0 m/s from the top of a 165 m building. How far does the stone travel during its 4th second of travel? 2. Relevant equations d= vit + 1/2at2 3. The attempt at a solution Vi = -5.0 m/s t = 4.0 s a = -9.81 m/s2 d = ? I tried it in the kinematics equation d= vit + 1/2at2 and the answer is wrong.
