A hanging spring stretches by 30.0 cm when an object of mass 490 g is hung on it at rest. We define its position as x = 0. The object is pulled down an additional 20.0 cm and released from rest to oscillate without friction. What is its position x at a moment 84.4 s later?
(b) Find the distance traveled by the vibrating object in part (a).
(c) Another hanging spring stretches by 30.5 cm when an object of mass 480 g is hung on it at rest. We define this new position as x = 0. This object is also pulled down an additional 20.0 cm and released from rest to oscillate without friction. Find its position x at a time 84.4 s later.
(d) Find the distance traveled by the vibrating object in part (c).
(e) Why are the answers to the parts (a) and (c) different by such a large percentage when the data in parts (a) and (c) are so similar and the answers to parts (b) and (d) are relatively close?
