99. We neglect air resistance, which justifies setting a = – g = –9.8 m/s 2 (taking down as the – y direction) for the duration of the motion. We are allowed to use Table 2-1 (with Δ y replacing Δ x ) because this is constant acceleration motion. When something is thrown straight up and is caught at the level it was thrown from (with a trajectory similar to that shown in Fig. 2-31), the time of flight t is half of its time of ascent t a , which is given by Eq. 2-18 with Δ y = H and v = 0 (indicating the maximum point).
