A ball is kicked at ground level with a speed of 15.0 m/s at an angle of 35.0° to the horizontal. How much later does it hit the ground?

  • physics -

    what is the vertical speed
    how long is it in the air.

    hf=hi+voi*t -1/2 g t^2
    but hf=hi=0
    heights are vertical

    voi*t=1/2 g t^2
    15sin35 t= 4.9t^2 solve for time t in the air.

  • physics -

    1.1 s
