The kinetic energy of a moving car is 50,000 J. What is the mass of a car with a given kinetic energy if it was moving at a speed of 10 m / s?
| December 15, 2020 | education
E kinetic = (mv ^ 2) / 2
From this formula, we can derive mass:
m = 2 * E kinetic / v ^ 2
m = (2 * 50,000 J) / (100 m ^ 2 / s ^ 2) = 1000 kg
Answer: 1000 kg
