The whale shark is the largest of all fish and can have the mass of three adult
elephants. Suppose that a crane is lifting a whale shark into a tank for delivery
to an aquarium. The crane must exert an unbalanced force of 2.5 x 104 N to
lift the shark from rest. If the shark's acceleration while being lifted equals
1.25 m/s², what is the shark's mass?

Respuesta :

Answer:

m = 20,000 kg

Explanation:

Force, [tex]F=2.5\times 10^4\ N[/tex]

Acceleration of the shark, [tex]a=1.25\ m/s^2[/tex]

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

[tex]m=\dfrac{F}{a}\\\\m=\dfrac{2.5\times 10^4}{1.25}\\\\m=20,000\ kg[/tex]

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