A golfer, standing on a fairway, hits a shot to a green that is elevated 5.39 m above where she is standing. If the ball leaves her club with a velocity of 43.1 m/s at an angle of 45.9 ° above the ground, find the time that the ball is in the air before it hits the green.

Answer 1

in the vertical:
hf=ho+vi*t-4.9t^2
5.39=43.1Sin45.9*t-4.9t^2 solve this quadratic for time in air, t.
