A resting eagle on a tree top finds a rabbit on the ground at a distance of 50 m from the base of the tree. The eagle applies a constant horizontal speed and uses gravity to descend. It catches the rabbit in 2.5 seconds.
a. What is the height of the tree top?
b. What is the constant horizontal speed of the eagle?
a. h = 0,5g*t^2 = 4.9*2.5^2 = 30.6 m.
b. d = V * t = 50 m.
V*2.5 = 50
V = 20 m/s.
