Question 11 • FL-1200700-Mathematics for College Algebra MIS

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

Answer
A
h(t) = –16t2 + v0t + 14
B
h(t) = –16t2 + 14t
C
h(t) = –16t2 + 14t + 14

Explanation

In h(t) = –16t² + v₀t + h₀, the initial vertical velocity is v₀ = 14 ft/s. The jump starts at ground level, so the initial height is h₀ = 0. Substituting gives h(t) = –16t² + 14t, which is choice B.
