You have two springs that arda* zhbqpn6y .c pn2.4p*k /mabp2h x9. cm)eke identical except that spring l is stiffer than spring e.pb )2x/h9mcmka* pk 2 $(k_1>k_2).$ On which spring
is more work done $(a)$ if they are stretched using the same force, $(b)$ if they are stretched the same distance?
参考答案: $(a)$ In this case, the same force is applied to both springs. Spring 1 will stretch less, and so more work is done on spring 2. $(b)$ In this case, both springs are stretched the same distance. It takes more force to stretch spring 1, and so more work is done on spring 1.
