Answer:
Explanation:
La energía mecánica total está dada por:
![E_(T) = E_(c) + E_(p)](https://img.qammunity.org/2021/formulas/mathematics/high-school/w7kyn8sw811j3jk1mzbi8ipgp0v45wr8vm.png)
![E_(T) = (1)/(2)mv^(2) + mgh](https://img.qammunity.org/2021/formulas/mathematics/high-school/yjy6bcval1d8dayazau9uxexea855fzxx0.png)
En donde:
m: es la masa = 150 g
v: es la velocidad = 0.8 m/s
h: es la altura = 25 m
g: es la gravedad = 9.81 m/s²
![E_(T) = (1)/(2)mv^(2) + mgh = (1)/(2)0.15 kg*(0.8 m/s)^(2) + 0.15 kg*9.81 m/s^(2)*25 m = 36.84 J](https://img.qammunity.org/2021/formulas/mathematics/high-school/1ti3kef3ef5mllcwa7cvukt9l6th6hp8hw.png)
Por lo tanto, la energía mecánica total es 36.84 J.
