Determine the initial speed of a falcon falling vertically on its prey

Determine the initial speed of a falcon falling vertically on its prey, if its speed at the moment of falling is 50 m / s, and the time of fall is 4.8 s.

Initial data: V (speed of the falcon at the moment of fall) = 50 m / s, t (duration of the fall of the falcon) = 4.8 s.

Constants: g (acceleration of gravity) = 10 m / s ^ 2 = a.

Let us express the initial speed of the falcon from the formula:

V = V0 + a * t = V0 + g * t.

V0 = V – g * t.

Let’s do the calculation:

V0 = 50 – 10 * 4.8 = 2 m / s.

Answer: The initial speed of the falcon before the sheer fall was 2 m / s.
