A 0.2 kg object that stretches a spring 6.5 cm
from its natural length when hanging at rest
oscillates with an amplitude of 1.5 cm.
The acceleration of gravity is 9.81 m/s2.
Find the total energy of the system.

  • Physics -

    The spring constant is
    k = 0.2*9.81 N/0.065 m = 30.18 N/m

    Total energy = (1/2) k A^2
    where A is the amplitude, 0.015 m
