Question

$2 + vt + h_0$ models the height, seconds after it is thrown. in this represents the initial vertical velocity represents the initial height of
from a height of 6 feet with velocity of 30 feet per second.
models the height of the ball, in
at the same time, mins little brother throws a baseball from a height of 4 feet with an initial vertical velocity of 20 feet per second. what polynomial models the height of this ball, in feet?
$-16t^2 + \square t + \square$

Explanation:

Step1: Identify given values

Initial velocity $v=20$ ft/s, initial height $h_0=4$ ft

Step2: Substitute into height formula

The standard height model is $h(t) = -16t^2 + vt + h_0$. Substitute the values:
$h(t) = -16t^2 + 20t + 4$

Answer:

$-16t^2 + 20t + 4$
