A block of mass 0.600 kg is suspended using a spring and a string as shown in the diagram. In this situation, the spring is stretched and its length is 12 cm. The relaxed length of the spring is 7 cm.
a.)Find the tension in the string. Start from a fundamental principle and show all work.
b.)What is the spring constant ks of the spring. Show all work.
Please show how you did it too...I'm studying.

Here are the answers to check your work:
a) 2.94 N
b) 102 N/m

I will assume the string has negligible mass
a) the weight of the block is the tension in the spring, or
0.600*9.81
5.886 N
This doesn't match the answers, is the block on an incline at an angle of 60 degrees?
b)using my answer of 5.886 N for the tension
the delta x is .05 m
using F=k*x
k=5.886/.05
or
117.7 N m
Again, doesn't match. Would you take a break from your studying and provide a diagram?
