4. The monument commemorating the Battle of San Jacinto in Texas stands almost 2.00 x 10-m
placed
on a spring
and is topped by a 2.00 x 105 kg star. Imagine that a 2.00 x 105 kg mass
platform. The platform requires 0.80 s to oscillate from the top
to the
bottom positions. What is
the spring constant of the spring supporting the platform?
