a) Compute the magnitude and direction of the resultant force taken counterclockwise from positive x axis, of the three forces. Use force resolution method to solve the problem.

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.
