Question

question 13
calculate the potential energy of a 2 kg box that is 12 m off the floor
o 235.2 j
o 24 j
o 117.6 j

Explanation:

Step1: Escribir la fórmula de energía potencial gravitacional

$$U = mgh$$
donde \(m = 2\space kg\), \(g = 9.8\space m/s^{2}\), \(h = 12\space m\)

Step2: Sustituir los valores en la fórmula

$$U=(2\space kg)(9.8\space m/s^{2})(12\space m)$$

Step3: Realizar el cálculo

$$U = 2\times9.8\times12\space J=235.2\space J$$

Answer:

235.2 J
