Figure 1.18 (Chapter 1) shows the Hoover Dam Bridge over

Answer: 7.436 s

Explanation:

This situation is related to vertical motion, specifically free fall and can be modelled by the following equation:

$y=y_{o}+V_{o} t+\frac{gt^{2}}{2}$

Where:

$y= 0m$ is the final height of the object (when it makes splash)

$y_{o}=271 m$ is the initial height of the object

$V_{o}=0 m/s$ is the initial velocity of the object (it was dropped)

$g=-9.8m/s^{2}$ is the acceleration due gravity (directed downwards)

$t$ is the time since the objecct is dropped until it makes splash

$0=y_{o}+0+\frac{gt^{2}}{2}$

Clearing $t$ :

$t=\sqrt{\frac{-2y_{o}}{g}}$

$t=\sqrt{\frac{-2(271 m)}{-9.8m/s^{2}}}$

Finally:

$t=7.436 s$
