Expert Solution
Step 1

As I had uploaded P13.18 in previous one where 13.17 asked, I am uploading 13.17 here.

 

Given,

m = 20 kg

Free length = L = 2.5 m

Spring constant = k = 200 N/m

 

Consider below diagram to understand initial and final length of the spring:

Mechanical Engineering homework question answer, step 1, image 1

 

From the given triangle, we know that,

OAOB = 34∴ 3OB = 34∴ OB (h)= 4 m 

 

Initial length = L1 = OA = 3 m

Final length = L2 = OB = 4 m
