**bobpursley**, Sunday, December 19, 2010 at 4:49pmLearn how to spell physics. I am reminded of the child who keep mispelling her last name.

initial vertical speed:

-20sin60

hf=hi+Viv*t-4.9t^2

0=30-20sin60 * t - 4.9t^2

solve for t. Notice you will have to use the quadratic equation.

distance= 20cos60 *t
