Respuesta:
Ep = 98 J Ec = 97.97 j
Explicación:
Ep = m.g.h
Ep = (5kg)(9.8m/s²)(2m)
Ep = 98 J
[tex]Vf = \sqrt{2gh} = \sqrt{2(9.8m/s^{2})(2m) } = \sqrt{39.2m^{2}/s^{2} } = 6.26m/s[/tex]
[tex]Ec = \frac{mv^{2} }{2} \\Ec = \frac{(5kg)(6.26m/s)^{2}}{2} \\Ec = \frac{(5kg)(39.19m^{2} /s^{2} )}{2} \\Ec = \frac{195.94J}{2}\\Ec = 97.97 J[/tex]
