The figure below shows a force versus position graph for a spring/block system.  If Fs=160N and the block is released at x = 12 cm (not shown on figure) how much work is done on the block by the spring as the block goes from x = + 8.0 cm to x = + 5.0 cm.  HInt:  Determine k from the graph.  Don't forget to convert from cm.

Expert Solution
Step 1

Solution:

 

From the given graph:

 

The slope of the graph between restoring force and displacement gives spring constant k as:

 

k=160-0-2-0=80 N.cm-1
