Question
A 1.0-kg object is suspended from a spring with k = 16 N/m. The mass is pulled 0.25 m downward from its equilibrium position and allowed to oscillate. What is the maximum kinetic energy of the object? A 1.0-kg object is suspended from a spring with k = 16 N/m.

A 1.0-kg object is suspended from a spring with k = 16 N/m. The mass is pulled 0.25 m downward from its equilibrium position and allowed to oscillate. What is the maximum kinetic energy of the object?Explanation / Answer
mass m = 1kg
Spring constant k = 16 N/m
Amplitude A 0.25 m
the maximum kinetic energy of the object = (1/2) kA 2
= 0.5x16 x0.25 2
= 0.5 J
