Physics

A golfer, standing on a fairway, hits a shot to a green that is elevated 5.50 m above the point where she is standing. If the ball leaves her club with a velocity of 46.0 m/s at an angle 0f 35.0º above the ground, find the time that the ball is in the air before it hits the green.

  1. Vi = 46 sin 35 = 26.4 m/s up

    5.5 = 0 + 26.4 t - 4.9 t^2

    4.9 t^2 -26.4 t + 5.5 = 0
    solve quadratic, use the longer time
