SUMMARY

A 4.0 kg block sliding at 5.0 m/s compresses a spring with a spring constant of 200 N/m on a frictionless surface. The maximum compression of the spring occurs when the kinetic energy of the block is fully converted into potential energy stored in the spring. Using the equations for kinetic energy (K.E. = 0.5 mv^2) and potential energy (P.E. = 0.5 kx^2), the block compresses the spring by 0.707 meters before coming to a stop and reversing direction.

PREREQUISITES
  • Understanding of kinetic energy and potential energy concepts
  • Familiarity with Hooke's Law and spring constants
  • Basic algebra for solving equations
  • Knowledge of conservation of energy principles
NEXT STEPS
  • Study the conservation of energy in mechanical systems
  • Learn about Hooke's Law and its applications in real-world scenarios
  • Explore the dynamics of frictionless surfaces in physics
  • Investigate the effects of varying spring constants on compression distances
USEFUL FOR

Students studying physics, particularly those focusing on mechanics, as well as educators looking for examples of energy conservation and spring dynamics.

Homework Statement



A 4.0 kg block slides along a frictionless horizontal surface at 5.0 m/s. It runs into and compresses a spring with a spring constant of 200 N/m. How far does it compress the spring before it stops and changes direction?

Homework Equations



P.E. = 0.5 kx^2
K.E. = 0.5 mv^2


The Attempt at a Solution



x = sqrt (mv^2/k) = 0.707 m?
