Question

un corp pe luna are greutatea de 150 N. Calculati masa corpului, stiind ca 9p=10 N/kg, iar 9p/9L = 6/1

Answer 1

G[pe luna]=150N;
⇒9p=10N/kg;
⇒9p/9L=6/1⇒54L=9p;
⇒54L=10N/kg⇒L=5,4N/kg;
⇒G=150N;⇒g=5,4N/kg⇒acceleratia gravitationala;
⇒m=G/g
⇒m=150N/5,4N/kg⇒se reduce N[newton] cu N[newton];
⇒m=150/5,4kg
⇒m=150/54/10[kg]
⇒m=150·10/54[kg]
⇒m=27,[7]kg⇒masa corpului;
