A shark weighing 250 kg swims at a speed of 18 km / h, determine its kinetic energy.
| June 2, 2021 | education
The kinetic energy of a moving shark is determined by the formula: Ek = (m * V ^ 2) / 2.
To begin with, we bring all the values into a single measurement system.
The shark’s speed is V = 18 km / h = 18 * 1000/3600 = 5 m / s.
Having all the data, let’s calculate the kinetic energy of the shark:
Ek = (m * V ^ 2) / 2 = (250 * 5 ^ 2) / 2 = 3125 J.
Answer: The kinetic energy of the shark is 3125 J.
