    Calculating the Depth of a Well and Velocity of a Rock Using Equations of Motion

    1. A rock is dropped into a well of an unknown depth. 20 seconds after the rock is dropped the splash is heard at the top of the well. What is the depth of the well? What is the velocity of the rock when it reached the bottom?2. X= Xo + Vo(t) + 0.5(a)(t^2) V= Vo + a(t) (V^2)= (Vo^2) + 2a(X-Xo)...
