Question 15

An elastic safety buffer in a train coupling system is compressed by a compressive force $F$ . The buffer behaves as an ideal spring obeying Hooke's law with spring constant $k$ . At maximum compression, the elastic potential energy stored in the buffer is $U$ .

Determine an expression for the spring constant $k\,$ in terms of $U\,$ and $F$ .
