Please let it be legible, thanks in advance!

ROVOW I Constants Penel lable A 480 g peregrine falcon reaches a speed of 60 m/s in a vertical dive called a stoop. (Figure 1) Part A Figure If we assume that the falcon speeds up under the influence of gravity only, what is the minimum height of the dive needed to achieve this speed? Express your answer with the appropriate units. 1 of 1 НА ? h - Value Units Submit Request Answer

Answer 1

m = 480 g = 0.48 kg

max_v = 60 m/s

Using the principle of energy conservation, Falcon reaches the speed of 60 m/s as the point where the potential energy is zero.

So,

KE = PE

½*m*v² = m*g*h

½* v² = g*h

½* 60² = 9.81*h

h = 183.5 m
