a soccer ball is kicked into the air at an angle of 38 degrees above the horizontal. The initial velocity of the ball is 30.0m/s.
How long was the ball in the air?
Determine the horizontal distance traveled by the ball?
what is the maximum height reached by the ball?

bobpursley,
find the vertical and horizontal components of initial velocity.
How long in air?
hf=hi+Viv*t4.9t^2
solve for t, knowing hf=hi=0
max height? at the top Vv is zero.
Vf=Vivgt
set Vf to zero, solve for t time to top, then hf=hi+viv^t4.9t^2, put the time to top in for t, solve for hf.
