Question

două corpuri au greutatea totală de 350 N.Stiind ca greutatea unui corp este de 120 N,determinați masa acestor corpi

Answer 1

$G_{total} = 350 N\\G_1=m_1g=120N\implies m_1=\frac{G_1}{g}=\frac{120N}{10\frac{N}{kg}}=12 kg\\G_2=m_2g=G_{total}-G_1=230N\implies m_2=\frac{G_2}{g}=\frac{230N}{10\frac{N}{kg}}=23kg\\m_1=12kg\\m_2=23kg$
