## Homework Statement

A block slides along an elevated track. The flat part has a length L = 0.2m and the object is released from rest from height h = 0.1m. The curved portion of the track is frictionless, but the flat part is rough with a friction coefficient μk = 0.15. Where does the object finally come

to rest? *Hint: use pseudowork to account for friction.

## Homework Equations

U = mgh =m9.8*0.1

## The Attempt at a Solution

i know that the object starts with U = mgh =m9.8*0.1=m0.98 but i have no idea what to do next.. and what's pseudowork?
