A soccer ball kicked on a level field has an initial vertical velocity component of 15 meters per second. Assuming the ball lands at the same height from which it was kicked, what is the total time the ball is in the air? [Neglect friction.]

make a HV chart!
you dont need horizontal for this problem so just do the vertical side.
Givens: (this is a shot problem)
Vi= 15m/s
a=9.8m/s^2
vf=0m/s
and T=?
so plug it into a=vfvi/t
9.8m/s= 015/x
So X= 1.53s
BUT!!!
it says the TOTAL time the ball is in the air. so you have to double the time. therfore the answer:
3.06seconds :)
