# An object with a mass of 4 kg is hanging from a spring with a constant of 2 (kg)/s^2. If the spring is stretched by  16 m, what is the net force on the object?

${F}_{n} = 7 , 24 N$

#### Explanation:

$G = m \cdot g$
$G = 4 \cdot 9 , 81 = 39 , 24 N$
$F = k \cdot \Delta x$
$F = 2 \cdot 16$
$F = 32 N$
${F}_{n} = 39 , 24 - 32$
${F}_{n} = 7 , 24 N$
