Step 1

Thank you for your question, there are four subparts given in the question and it is not mentioned which subpart is to be answered. As per our policy we are answering first three subparts.

Step 2

The value of mass m = 0.3 kg

The radius of circular guide R = 2.2 m

The value of spring constant k = 145 N/m

The unstretched length of spring = 0.68 R = 1.496 m
