Question

A car with a mass of 1,000 kg is moving at a speed of 20 m/s. What is the car's kinetic energy?

Answer 1

The answer would be 200000 J. the equation for kinetic energy is 1/2 mass times velocity squared. 1/2 of 1,000 is 500. and 20*20 is 400. So, multiply 400 by 500, and that gives you your answer,
