A small red car sits at left on the top of a table with a blue arrow A pointing up from the car and with a blue arrow B pointing down from the car. A dotted line in front of the car is labeled Start. A blue arrow point right from the car to point C about midway along the table, and a yellow arrow labeled 0.25 meters intersects this blue arrow. A yellow arrow past point C is labeled 0.5 meters. A pulley at the end of the table is connected to the front of the car and to a weight made from 2 washers hanging off the right end of the table. A blue arrow D points to the ground just off the right end of the table. A bracket shows the weight to be 0.5 meters off the ground. The normal force acting upon the car is best represented by arrow . The force of gravity acting upon the washers is best represented by arrow . The applied force on the car is best represented by arrow .

Ahanging spring stretches by 35.0 cm when an object of mass 450 g is hung on it at rest. in this situation, we define its position as x = 0. the object is pulled down an additional 18.0 cm and released from rest to oscillate without friction. what is its position x at a moment 84.4 s later? express your answer in cm.
