2. A long measuring stick rests against the wall in a physics laboratory with its 200-cm end at the floor. A cockroach lands on its 100-cm mark and crawls randomly along the stick. It first walks 15 cm toward the floor, then it walks 56 cm toward the wall, then it walks 3 cm towards the floor again. Then, after a brief stop, it continues for 25 cm toward the floor and then, again, it crawls up 19 cm toward the wall before coming to a complete rest. Find the vector of its total displacement and its final resting position on the stick.
