Question

Ce masă are un corp cu greutatea de 98 de Newton?

Answer 1

g=9,8
G=m×g
m=G÷g
m=98N÷9,8 N/kg
m=10kg

Answer 2

$G=98 \ N \\ g=9,8 \ N/kg \\ \boxed{m-?} \\ \bold{Rezolvare:} \\ \boxed{G=m \cdot g} \\ \Rightarrow m= \frac{G}{g} \\ m= \frac{98 \ N}{9,8 \ N/kg} \\ \Rightarrow \boxed{m=10 \ kg}.$
