A 050-Kg Object Is Attached to an Ideal Spring of Spring

Short Answer

A 0.50-kg object is attached to an ideal spring of spring constant (force constant) 20 N/m
along a horizontal, frictionless surface. The object oscillates in simple harmonic motion
and has a speed of 1.5 m/s at the equilibrium position. What are (a) the total energy and
(b) the amplitude of vibration of the system?
