Calculating the loss of mechanical energy

A block of mass M slides along a horizontal table with speed Vo. At x=0 it hits a spring constant k and begins to experience a frictional force. The coefficient of friction is a variable and is given by u=bx, where b is a constant. Find the loss in mechanical energy when the block has come momentarily to rest.

In order for the block to come to a stop, all of the initial kinetic energy must be transferred to friction. ...

Solution Summary

Loss in mechanical energy is shown.
