 Homework Statement:
 A dishonest woman Sues a poor innocent young man, claiming that he intentionally dropped (free fall) a stone from the top of a bridge which is 6.0 m above the ground, which damaged the trunk of her car. The complainant admits that she was driving at the maximum speed allowed of 100 km / h. You are called as an expert in this case (you are a physicist, right?). By making the necessary approximations, will you be able to save the young man ?
 Relevant Equations:

Y=Yo+vot+0,5a(t^2)
X=Vot+Xo
0=64.9(t^2)
0=27,7t+Xo
From the first equation,
T= 1.10s
From the second equation,
(Xo/27,7)=t
0=64.9((Xo/27,7)^2)
We solve for Xo = 30,65
Now, we have
X=27,7t+30,65
If t=1,10
Then , 27,7(1,10)+30,65=0,18 which is not equal to 0.
Which means the stone hits the ground first.
Is my answer correct ?
