Question

The Blue Whale is the largest animal to have ever lived. As an adult it is as long as three school buses added together. A 170,000 kg Blue Whale cruises along at a modest pace. If it has 890,000 Joules of kinetic energy, what is its cruising speed?

Answer 1

Step-by-step explanation:

Kinetic energy = 1/2 m v^2

sqrt ( 2 * KE/m) = v

sqrt (2 * 890 000 / 170 000 ) = 3.2 m/s
