Răspuns:
P = 0,08 CP
Rezolvare:
m = 60 kg
h = 18 m
t = 3 min = 180 s
_____________
P = ? (CP)
F = G = mg = 60 × 10 = 600 N
[tex]P=\frac{L}{t}=\frac{Fd}{t}=\frac{Fh}{t}=\frac{600\times18}{180}=600\times0,1=60\:W=\bf0,08\:CP\\[/tex]
______________
Pentru rezolvarea acestui exercițiu am folosit formula puterii mecanice:[tex]\bf\red{\boxed{P=\frac{L}{t}}}\\[/tex]
De asemenea:
[tex]\bf\purple{\boxed{1\:CP=736\:W}}\\[/tex]
Succes! ❀
