A bird flying horizontally 100[m] above the ground flies exactly overhead with respect to an observer on the ground. After waiting 10 seconds, the observer measures the angle 0 that the bird makes with respect to the vertical. How fast is the bird flying? A) 10 cos(8) [m/s] B) 10 sin(0) [m/s] Cy 10 tan(0) [m/s] Đ) 100 cos(6) [m/sj E) 100 sin(0) [mls] F) 100 tan(0) [m/s]
