An object with a mass of 6 kg is hanging from a spring with a constant of 4 (kg)/s^2. If the spring is stretched by 8 m, what is the net force on the object?

$26.86 \setminus N \setminus \quad \left(\setminus \textrm{\mathrm{do} w n w a r d}\right)$

Explanation:

Gravitational force on the object

$= m g = 6 \setminus \times 9.81 = 58.86 \setminus N$

Spring force on the object

$= k x = 4 \setminus \times 8 = 32 \setminus N$

Net force on the object

$= \setminus \textrm{\mathrm{do} w n w a r d g r a v i t a t i o n a l f \mathmr{and} c e o n m a s s} - \setminus \textrm{u p w a r d s p r \in g f \mathmr{and} c e}$

$= 58.86 - 32$

$= 26.86 \setminus N \setminus \quad \left(\setminus \textrm{\mathrm{do} w n w a r d}\right)$
