Answer:

m = 20,000 kg

Explanation:

Force, $F=2.5\times 10^4\ N$

Acceleration of the shark, $a=1.25\ m/s^2$

It is required to find the mass of the shark. Let m is the mass. Using second law of motion to find it as follows :

F = ma

Putting the value of F and a to find m

$m=\dfrac{F}{a}\\\\m=\dfrac{2.5\times 10^4}{1.25}\\\\m=20,000\ kg$

So, the shark's mass is 20,000 kg.
