Problem

The suspension system of a car contains springs that are compressed to absorb energy. One of the car’s springs (with a spring constant of 85,000N/m) is compressed 0.019m as the car moves up and down on a bumpy road.
Calculate the elastic potential energy of the compressed car spring.
Round your answer to the nearest integer.
  • 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
