A) A mass on a spring vibrates in simple harmonic motion at a
frequency of 4.0 Hz and an amplitude of 8.0 cm. If a timer is
started when its displacement from equilibrium is a maximum (hence
x = 8 cm when t = 0), what is the displacement of the mass when t =
3.7 s?
B) A mass of 4.0 kg, resting on a horizontal, frictionless
surface, is attached on the right to a horizontal spring with
spring...

Consider a block attached to a horizontal spring that

(b) moving towards the equilibrium position
c) at equilibrium position
(d) maximum displacement

1. An object-spring system moving with simple harmonic motion
(SHM) has an amplitude A.
(a) What is the total energy of the system in terms of k and A
only?
(b) Suppose at a certain instant the kinetic energy is twice the
