Crickets can jump with a vertical velocity of up to 14 ft/s. Which equation models the height of such a jump, in feet, after t seconds? h(t) = –16t2 + v0t + h0

h(t) = –16t2 + v0t + 14
h(t) = –16t2 + 14t

h(t) = –16t2 + 14t + 14
What is the maximum height the cricket reaches? Round to the nearest thousandth.
h =
feet
