A ball is thrown straight up with an initial velocity of 17. 2 m/s (assume air resistance is negligible and take the point of release to be y0=0).  Calculate the displacement of the ball (in m) after 0.5 s.

y = yo + v0 t - 1/2 a t2                    vo = initial velocity     a = acceleration of gravity   t = time

    =  0   + 17.2 (0.5) - 12 (32)(0.52)  = __________ meters
