h1(t) =

h2(t) =

When does ball 1 reach the ground? Round to the nearest hundredth. _____seconds

When does ball 2 reach the ground? Round to the nearest hundredth. _____seconds

- algebra1 HELP PLEASE Thanks you!! -
**Reiny**, Monday, July 8, 2013 at 2:17pmh1(t) = -16t^2 + 100

h2(t) = -16t^2 + 210

when ball 1 reaches ground, h1(t) = 0

16t^2 = 100

t^2 = 100/16

t = √(100/16) = 10/4 = 5/2 seconds

do the 2nd the same way
