For a spring force-compression graph is shown in figure. A body of mass 5 kg moving with a speed of 8 ms–1 collides the The maximum compression in the spring is Image related to
2 m
4 m
6 m
8 m

Solution:

Using this graph we can find value of Spring constant.

F = - K.x

So, K = 80 N/m

Kinetic Energy of the block will convert into spring potential energy

so, ½mv² = ½ k x²

solving x = 2 m
