QuestionFind the ball's velocity when it first reaches $880 \mathrm{ft}$, given $s(t)=-16 t^{2}+256 t$.

Studdy Solution
Calculate the velocity.
$$v(5) = -32*5 +256 =96 \, \mathrm{ft/s}$$The velocity of the ball when it first reaches a vertical height of $880 \, \mathrm{ft}$ is $96 \, \mathrm{ft/s}$.
