Free Fall!

Classical Mechanics Level 2

At time \(t=0\), apple 1 is dropped from a bridge onto a roadway beneath the bridge. Somewhat later, apple 2 is thrown down from the same height. The figure gives the vertical positions y of the apples versus t during falling, until both apples have hit the roadway. With approximately what speed is apple 2 thrown down? Take \(g=9.8 \text{ m/s}^2 \).
