A mass-spring system oscillates on a
frictionless horizontal surface in simple
harmonic motion with an amplitude A =
0.16 m. At what position (x = ?) would
the kinetic energy of the system be
equal to three times its elastic potential
energy (K = 3U)?
At x = +0.08 m
At x = +0.04 m
At x = +0.1 m
At x = +0.05 m
At x = +0.025 m
Consider a place where the gravity is
one-fourth the gravity on Earth (g' =
g/4), then the frequency of oscillation
of a simple pendulum in that place, f',
as compared to its frequency on earth
is:
