Pick the other choice. We are given the initial horizontal velocity and the time. The variables that are implied are the initial vertical velocity (0m/s because it was launched horizontally, not verticaly), the horizontal acceleration (0m/s^2 because there is no horizontal force after it is in the air), the vertical acceleration (-9.8m/s^2 because of gravity).

What equation is necessary to solve for the horizontal displacement of the baseball as it lands if we know what v(ix), a(x), and t is?
120
a=(vf-vi)/t
d=v(ix)*t+(1/2)a(x)*t^2
a=(vf^2-vi^2)/2d
v=d/t
