Recall,

If

Apply Newton's second law to understand the amount of friction you need to overcome in order to push the particle,

Moreover, consider the situation at two instants: (i) at rest, and (ii) having been accelerated to

Hence,

**right kinetic friction coefficient (meanie)!**

Moreover,

Hence,

where
