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. Figure below gives the vertical position, y of the apples versus t, time of the falling, until both apples have hit the roadway. The scaling is set by ts= 2.0 s. With approximately what speed was apple 2 thrown down? |
