A hawk flying at 18 m/s at an altitude of 190 m accidentally drops its prey. The parabolic trajectory of the falling prey is described by the equation y = 190 – x²154 until it hits the ground, where y is - the height above the ground and x is the horizontal distance traveled in meters. Let D be the distance traveled by the prey from the time it is dropped until the time it hits the ground. dx , where a = and b = Therefore the distance traveled by the prey is equal to
The horizontal distance or range (R) of an object thrown at an angle 8 from the horizontal is represented by the equation below where vo is the initial velocity as the object leaves the hand, in feet per second. If vo = 2500 feet per second and e is changed from 13° to 14°, use differentials to approximate the change in range, in feet.
