-Neglecting air resistance, the distance h traveled by a free-falling object in time t is given by the formula $\mathrm { h } = 16 \mathrm { t } ^ { 2 }$ . Use this formula to find the time of free fall for a parachutist who falls 3519 feet before opening her parachute. Round your answer to the nearest tenth of a second.
A)3.7 sec
B)110 sec
C)14.8 sec
D)237.3 sec

Given the formula $h = 16t^2$ and $h = 3519$ feet, we solve for $t$ by substituting $3519$ for $h$: $3519 = 16t^2$. Solving for $t$, we get $t = \sqrt{\frac{3519}{16}} \approx 14.8$ seconds.
