A body moving with uniform acceleration has a velocity of 16 cm/s when its x coordinate is 3.52 cm. If its x coordinate 2.4 s later is –2.45 cm, what is the x-component of its acceleration? Answer in units of cm/s2.

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.
