Humpback whales sometimes catch fish by swimming rapidly in a circle, blowing a curtain of bubbles that confuses a school of fis

andre [41]

Answer:

1.2 x $10^4$ N

Explanation:

The centripetal force of a body moving in a circle is given by:

Centripetal force = $\frac{Mv^2}{r}$

where M = mass of the object, v = velocity with which the object is moving, and r = radius of the circle.

In this case, M = 25,000 kg, v = 2.0 m/s, and r = 8.2 m. Hence;

Centripetal force generated by the whale = 25,000 x 2^2/8.2

= 12,195.12 N = 1.2 x $10^4$ N to two significant digits.
