With what speed does it strike the water?

**bobpursley**, Thursday, January 14, 2010 at 5:49pmIf the initial velocity is horizontal, it has not influence on the time of fall.

Time of fall is determined by the height, and by gravity.

h=1/2 g t^2

solve for t, time.

**Alan Thomas**, Thursday, January 14, 2010 at 5:51pmHow would I calculate the speed?

- Physics -
**bobpursley**, Thursday, January 14, 2010 at 5:53pmthe vertical speed is

vf= g *time

the horizontal speed is the kicking speed.

Vftotal=sqrt (Vh^2+ Vvf^2)
