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
15sin35.
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
