A hungry 11.5 kg predator fish is coasting from west to east at 75.0 cm/s when it suddenly swallows a 1.25 kg fish swimming from

Oksi-84 [34.3K]

Answer with Explanation:

We are given that

Mass,m=11.5 kg

$v_x=75 cm/s=0.75 m/s,v_y=0$

1 m=100 cm

$m'=1.25 kg$

$v'_x=0,v'_y=3.6 m/s$

According to law of conservation momentum along east west direction

$11.5\times 0.75+1.25(0)=(11.5+1.25)V_x$

$8.625=12.75V_x$

$V_x=\frac{8.625}{12.75}$

$V_x=0.68 m/s$

According to law of conservation of momentum along north south direction

$11.5(0)+1.25(3.6)=(11.5+1.25)V_y$

$4.5=12.75V_y$

$V_y=\frac{4.5}{12.75}=0.35 m/s$

$V=\sqrt{V^2_x+V^2_y}$

$V=\sqrt{(0.68)^2+(0.35)^2}$

$V=0.76 m/s$

Direction, $\theta=tan^{-1}(\frac{V_y}{V_x})$

$\theta=tan^{-1}(\frac{0.35}{0.68})$

$\theta=27.23^{\circ}$
