if you know calc

just take the derivative of H(t) wrt

and set it to zero that is H'(t)=0

anonymous · Answer

I think your v will be 34 and you s 0

anonymous · Answer

if you dont know calce then  set h(t) to zero 

-16t2 + 34t=0 

Solve for t

from this you can easily calculate how long the ball was in the air for.

take half the time the ball was in the air call it ht for hangtime   ht/2


and plug it back into your equations
-16(ht/2)2 + 34(ht/2)
