The x component of velocity is 9.0m/s, y component is zero initially. a = - 9.8m / s2

Since the jumper lands at a - 45-degree angle the final Vy must have the same magnitude as the final Vx. V f2 = V 02 + 2ad Plugging in values: (-9.0m/s) 2 = 0m/s+2 (-9.8m / s2) d The height difference, d is equal to |-4.13| or 4.13 m.
