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.
+37146 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
