Multiple Choice

Solve.
-Ron throws a ball straight up with an initial speed of 70 feet per second from a height of 3 feet. Find parametric equations that describe the motion of the ball as a function of time. How long is the ball in the air? When is the ball at its maximum height? What is the maximum height of the ball?

A) $x = 0$ and $y = - 16 t ^ { 2 } + 40 t + 6$
$5.284 \mathrm { sec } , 1.25 \mathrm { sec }$
25 feet

B) $x = 0$ and $y = - 16 t ^ { 2 } + 40 t + 6$
$2.34 \mathrm { sec } , 1.25 \mathrm { sec }$ ,
$5.99$ feet

C) $\begin{array}{l}x=0 \text { and } y=-16 t^{2}+40 t+6 \\4.679 \mathrm{sec}, 1.25 \mathrm{sec} \\181.21 \text { feet }\end{array}$

D) $x = 0$ and $y = - 16 t ^ { 2 } + 40 t + 6$
$2.642 \mathrm { sec } , 1.25 \mathrm { sec }$
$181.21$ feet
31 feet
