Question

Va rog URGENT!!
Dau coroană!!

Answer 1

Energia cinetica = $\frac{mv}{2²}$
Ecautoturism=900*1296*10⁵/2=45*1296*10⁶=5832*10⁷
36km/h = 3600*36*10³=1296*10⁵ m/s.
Ecelefant=4500*10²/2=225*10³
Ecstrut=3*10² ori 216*10⁴/2=3*108*10⁶= 324*10⁶J
3q = 3*10²
0.6 km/h = 6*10⁻¹ ori 3600 ori 10³ = 6*36*10⁴=216*10⁴ J
Ecatlet= 7*10²/2= 350J
700 hg = 70kg = 7*10¹ kg
1dam/s = 10m/s

Ecautoturism>Ecstrut>Ecelefant>Ecatlet

Ec=energia cinetica iar dupa am adaugat numele corpului.
