A Hawk Flying at an Altitude Of $121 \mathrm {~m}$ Accidentally Drops Its Prey

True/False

A hawk flying at an altitude of $121 \mathrm {~m}$ accidentally drops its prey. The parabolic trajectory of the falling prey is described by the equation
$$y = 121 - \frac { x ^ { 2 } } { 64 }$$
until it hits the ground, where $y$ is its height above the ground and $x$ is the horizontal distance traveled in meters.
True or False?
The distance traveled by the prey from the time it is dropped until the time it hits the ground is approximately $156.532 \mathrm {~m}$ .
