Initial velocity for football field goal from 45m at 35°

[Phy.Student]

Homework Statement

A football player kicks a field goal from a distance of 45m from the goalpost.
The football is launched at 35 degrees above horizontal.
What initial velocity is required so that the football just clears the goalpost crossbar that is 3.1m above the ground? ignore air resistance and dimension of ball.

Homework Equations

D = Vi(t) + 1/2(a) (t^2)

Vf^2 = Vi^2 + 2(a)(D)

Vf= Vi + (a)(t)
