Distance s(ft) of ball from the ground after t sec is s=96+80t-16t^(2)

1) how many sec. will the ball pass the top of the building when it is coming down?

How would I solve this?

**bobpursley**, Tuesday, September 7, 2010 at 11:11pmset s(t) to 96 and solve.

96=96+80t-16t^2

solve for t

**Amy~**, Tuesday, September 7, 2010 at 11:19pmwhy would I set 96 for s(t) because that's the height of the building ?

but it's when the ball passes the top of the building

Also I tried solving it I got to

-16t(t-5)= 0 what should I do next
