The work done on both Elastic X and Elastic Y is 25.2 J.
The work done on the Elastic X is calculated as follows;
W = ¹/₂fx
where;
W = ¹/₂(42)(1.2)
W = 25.2 J
The work done on the Elastic Y is calculated as follows;
W = ¹/₂fx
where;
W = ¹/₂(24)(2.1)
W = 25.2 J
Thus, the work done on both Elastic X and Elastic Y is 25.2 J.
