Question17. A soccer ball is kicked with an initial vertical velocity of $64 \mathrm{ft} / \mathrm{s}$ . The function $h(t)=-16 t^{2}+64$ models the height $h$ (in feet) of the soccer ball at time $t$ (in seconds). When does the soccer ball reach the ground?

Studdy Solution
Interpret the solution. Since time cannot be negative in this context, we only consider the positive value:
$t = 2$
The soccer ball reaches the ground at:
$\boxed{2} \text{ seconds}$
