A fish and bird are moving as shown in figure. Find the velocity of bird as observed by fish.

Answer:

Solution:

$\frac{x _{B f}}{μ _{f}} = \frac{y}{1} + \frac{x}{μ} \Rightarrow x_{B f} = μ y + x$

$\frac{dx _{Bf}}{dt} = μ \frac{dy}{dt} + \frac{dx}{dt} = \frac{4}{3} (- 12) + 24$ $v = 8 m / s$ upward
