What is the kinetic energy of a 20 kg body moving at a speed of 4 m / s?
| June 11, 2021 | education
Initial data: m (body weight) = 20 kg; V (body speed) = 4 m / s.
The kinetic energy of the body can be calculated using the formula:
Ek = m * V ^ 2/2.
Let’s do the calculation:
Ek = 20 * 4 ^ 2/2 = 20 * 16/2 = 320/2 = 160 J.
Answer: The kinetic energy of the body is 160 J.
