String and spring over block

The blue box in the figure has a mass of 38 kg. To the nearest newton, what is the tension in the rope?

If the spring has a spring constant of 515 N/m, to the nearest tenth of a cm how far is it stretched?

See the attached file.

Solution Preview

Assuming the usual assumptions, that there is not friction, massless rope and spring, the rope must have the same tension T in all its parts. Therefore 2T from the two branches of the rope ...

Solution Summary

The solution assists with determining the tension in the rope and how far the spring constant has stretched.
