The problem statement, all variables and given/known data[/b] A football is kicked at ground level with a speed of 18.2 at an angle of 43.1 to the horizontal. How much later does it hit the ground? Relevant equations[/b] I tried using y = y_o + V_o*t + .5(a)(t)^2 Can anyone help me solve this? It seems like it would be relatively easy but I can't seem to get the correct answer.. Thanks!
