Answer:
d=117.2845834m
Explanation:
Let's start out with the vertical components
vi=0, vf=?, a=9.8, x=120, t=?
Let's find how long the rock was falling.
x=vi*t+.5*a*t^2
120=0+.5*9.8*t^2
120=4.9*t^2
t=4.9487166s
Since we know the horizontal velocity is constant, we use the formula v=d/t
23.7=d/4.9487166
d=117.2845834m
