1. The problem statement, all variables and given/known data
A 0.25 kg ball, initially at rest, is hit with a bat in the x-direction while held 1.00 meter above the ground. If the ball hits the ground 20 meters away and was in contact with the bat for 0.10 sec, What average force was exerted on the ball during the contact time??



2. Relevant equations
deltaX= 1/2at^2


3. The attempt at a solution
I have tried to get the time, and then velocity in the x-direction but I am stock since I just can't figure out the acceleration.
aNY HELP!!!!

Have you tried using the law of Impulses?
[itex]
\large
\Delta{\vec{p}} = \vec{\overline{F}}\cdot\Delta{t}
[/itex]
