Question

Doua corpuri au greutatea totala de 350N . Stiind ca greutatea unui corp este de 120N determinati masa acestor corpuri.

Answer 1

a-primul corp
b-al doilea
a+b=350 N
 b- 120 N
a+120N=350N =>a=230N
G1=m1*g =>m1=$\frac{G1}{g} = \frac{230N}{10N/kg} =\ \textgreater \ m1=23kg$
b=120N
G2=m2*g =>m2=$\frac{G2}{g} = \frac{120N}{10N/kg} = 12kg =\ \textgreater \ m2=12kg$
m=m1+m2
m=23kg+12kg= 35 kg
Masa e 35 kg.
