Question
what is the kinetic energy of a go - cart with a mass of 150 kg and a speed of 20 m/s?
3,000 j
30,000 j
60,000 j
Step1: Escribir la fórmula de energía cinética
La fórmula de energía cinética es \( KE=\frac{1}{2}mv^{2} \), donde \( m \) es la masa y \( v \) es la velocidad.
Step2: Sustituir los valores dados
Dado que \( m = 150\,\text{kg} \) y \( v = 20\,\text{m/s} \), sustituimos en la fórmula:
