Desde la parte más alta de un edificio a 25 m una persona lanza hacia la base un objeto de 150 g con una velocidad de 0.8 m por
ANTONII [103]

Answer:

E_{T} = 36.84 J        

Step-by-step explanation:

La energía mecánica total está dada por:

E_{T} = E_{c} + E_{p}

E_{T} = \frac{1}{2}mv^{2} + mgh

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} = \frac{1}{2}mv^{2} + mgh = \frac{1}{2}0.15 kg*(0.8 m/s)^{2} + 0.15 kg*9.81 m/s^{2}*25 m = 36.84 J

Por lo tanto, la energía mecánica total es 36.84 J.

Espero que te sea de utilidad!
