A Hawk Flying at an Altitude Of $121$ M Accidentally Drops Its Prey

True/False

A hawk flying at an altitude of $121$ 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 $156.532$ m.
