Question

A 20-kg box hangs from 2 strings in the same plane. 1 goes up and to left 30 degrees above horizontal. The other to the right @ 30 degree from vertical. A spring is attached to the bottom of the box; the other end of the spring is connected to a second, 10-kg box that sits on table below the 1st box. The spring is vertical with a spring constant of 100N/m & is stretched 25cm from equil. What are the magnitudes of the gravitational, spring, & tension forces?
