Too lazy to walk to the mailbox

Bob is dropping a package out of a 3rd story window so that the mail truck can catch the package. The mail truck has his sunroof open and the building window is 11 meters from sunroof level. The mail truck must travel from rest 105 meters to get to the drop zone. How fast will the mail truck be traveling if he catches the package (m/s).

assumptions: Neglect air resistance The truck has uniform acceleration g = 9.8 m/s/s
