You're 6.0 m from one wall of a house. You want to toss a ball to your friend who is 6.0 m from the opposite wall. The throw and catch each occur 1.0 m above the ground. V Assume the overhang of the roof is negligible, so that you may assume the edge of the roof is 6.0 m from you and 6.0 m from your friend.
What minimum speed will allow the ball to clear the roof?
okay i figured out this much so far:
delta x= 9m
9= (Vo cos theta)T
delta y=5
5= (Vo sin theta)T- .5gt^2
Vy=Vosintheta - gt=0
t=Vosintheta / g
and now i know i am suppose to plug in T into the x equation and y equation to solve for Vo, but i can't figure out to do that?
