Answer:
1.2 x N
Explanation:
The centripetal force of a body moving in a circle is given by:
Centripetal force =
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 N to two significant digits.
