a block of mass M slides along a horizontal table with speed v0 at x=0 it hits a spring with spring constant k and begins to experience a friction force. the coefficient of friction is variable and is given by u=bx where b is a constnat.(adsbygoogle = window.adsbygoogle || []).push({});

find the loss in mechanical energy when the block has first come momentarily to rest.

i got to this equation (im not sure it's correct):

fx+kx^2/2-mv0^2/2

is this correct?
