Question

a) A hanging 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? (b) Find the distance traveled
by the vibrating object in part (a). (c) What If? Another
hanging spring stretches by 35.5 cm when an object of
mass 440 g is hung on it at rest. We define this new
position as x = 0. This object is also pulled down an
additional 18.0 cm and released from rest to oscillate
without friction. Find its position 84.4 s later. (d) Find
the distance traveled by the object in part (c). (e) Why
are the answers to parts (a) and (c) so different when
the initial data in parts (a) and (c) are so similar and
the answers to parts (b) and (d) are relatively close?
Does this circumstance reveal a fundamental difficulty
in calculating the future?
