Will give medal!! Help! -Both Ryan and Deland throw a tennis ball into the air. At any time, t, the height, h, of Ryan’s ball is modeled by the equation h = –16t2 + 30t + 5. Deland throws his tennis ball with the same acceleration, a, from the same initial height, h, but with an initial velocity, v, double that of Justin’s. Which equation best models the height of Deland’s rocket?

FORMULA: h(t) = at2 + vt + h0

Answer Choices:
h = –16t2 + 30t + 10
h = –32t2 + 60t + 10
h = –32t2 + 30t + 5
h = –16t2 + 60t + 5
