Problem

A student building a game wants to launch a 0.0060kg marble at 11m/s using a spring. The spring constant is 380N/m. Assume no mechanical energy is lost from the system.
Calculate how far the spring should be compressed in order to achieve the desired speed.
Round your answer to the nearest thousandth.
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
  • an exact decimal, like 0.75
  • a multiple of pi, like 12 pi or 2/3 pi
