After a golf ball is hit it takes off with an initial speed of 22.0 m/s and at an angle of 38.0° with respect to the horizontal. The golf field is flat and horizontal. Neglecting air resistance how far will the golf ball fly?

find time in air:

hf=hi+22Sin38*t-4.9t^2

solve for time in the air, t, when height final hf is zero.

horizontal: distance=2cos38 * timeinair.

Max altitude?

1) What is altitude at TimeinAir/2 ?

hf=hi+22Sin38*t-4.9(t/2)^2
