A 050-Kg Box Is Attached to an Ideal Spring of Force

question 82

Short Answer

A 0.50-kg box is attached to an ideal spring of force constant (spring constant) 20 N/m on
a horizontal, frictionless floor. The box oscillates in simple harmonic motion and has a
speed of 1.5 m/s at the equilibrium position.
(a) What is the amplitude of vibration?
(b) At what distance from the equilibrium position are the kinetic energy and the potential
energy the same?
