In the future, high school students living on the moon have to try to play ultimate frisbee outside, since all three biodomes are already booked. Unfortunately, since there is not an atmosphere like Earth's on the moon, there is not lift to keep the frisbee from falling, even with a smaller weight force caused by the moon's smaller mass.
The initial velocity is only in the x direction. The final velocity is still affected by the unchanging x velocity, but also by the new y velocity calculated from the kinematic equation Vf^2 = Vi^2 + 2a(Yf-Yi), where a is acceleration by gravity (.166g) in this case, and change in Y is h.
