You have two springs i1q (aagc t:na6y9t;q z wl7 g c1ln5f-6 9llm e5o:xr+q.lkemthat are identical except that spring l is stiffer than sprmeeqll.7+55glr 9fw1o6xc- lzl k:m n ing 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.
