An undamped 2.74-kg horizontal spring oscillator has a spring constant of 32.2 N/m. While oscillating, it is found to have a speed of 3.01 m/s as it passes through its equilibrium position.
A. What is its amplitude of oscillation?
B.What is the oscillator's total mechanical energy as it passes through a position that is 0.527 of the amplitude away from the equilibrium position?
a)Kinetic energy is given as:
Ek = m ∙ v² / 2
Ek = 2.74 ∙ 3.01² / 2
Ek = 12.41 J
Now (1/2)kA2 = 12.41 J
(1/2) 32.2 x A2 = 12.41
A = 0.87 m (Required amplitude of oscillation)
b)
Since mechanical energy remains constant hence energy at position that is 0.527 of the amplitude away from the equilibrium position = 12.41 J
