Question

la ce inaltime s-a ridicat un elicopter cu masa de 7,5t, daca energia lui potentionala sa marit cu 15MJ?

Answer 1

m=7,5 t=7500 kg

Ep=15 MJ=15000000 J

h=?

g=10 N/kg

h=Ep/m•g

h=15000000 J:7500 kg•10 N/kg

h=200 m

Answer 2

Stim:m=7,5 ;t=7500kg;ep=15 MJ=15000000 J
Fie g=10N/kg
h=Ep/m×g
Ei si: h=15000000J/7500kg×10N/kg
h=200 m
Si gata problema!
