Physics: How much work, in kj, can a spring whose spring constant is 4 kn/cm produce after it has been compressed 3 cm from its unloaded length?

How much work, in kj, can a spring whose spring constant

work done on compressing spring will be 135 j

Explanation:

We have given spring constant $K=3kN/cm=3\times \frac{1000N}{10^{-2}m}=3\times 10^5N/m$ ( As 1 kN = 1000N and 1 m = 100 cm )

Spring is compressed by 3 cm

As 1 m = 100 cm

So $3cm=3\times 10^{-2}m$

Work done on compressing spring is given by $W=\frac{1}{2}kx^2$

So $W=\frac{1}{2}\times 3\times 10^{5}\times (3\times 10^{-2})^2=13.5\times 10=135J$

So work done on compressing spring will be 135 j

El paquete golpearía el suelo a la velocidad de acuerdo con la aceleración de la gravedad. La velocidad también dependería de la masa del paquete.
