A 25-gram block is resting on a horizontal, frictionless surface and is attached to a horizontal spring of k = 210 N/m. The spring is stretched so that the block is 27 cm away from the spring’s equilibrium position and released from rest.
a) What is the velocity of the block when it passes through the equilibrium point?
b) At what distance from equilibrium is the spring’s potential energy equal to the block’s kinetic energy?
c) Suppose the block has a speed of 21 m/s when it passes through the equilibrium point for the first time, how much work is done by the force of kinetic friction during that first part of the block’s motion?

A mass resting on a horizontal, frictionless surface is attached
to one end of a spring; the other end is fixed to a wall. It takes
3.7 J of work to compress the spring by 0.14 m . If the spring is
compressed, and the mass is released from rest, it experiences a
maximum acceleration of 12 m/s2.
Find the value of the spring constant.

A block of wood slides on a frictionless horizontal surface. It
is attached to a spring and oscillates with a period of 0.8 s. A
second block rests on top of the first. The coefficient of static
friction between the two blocks is 0.25.
If the amplitude of oscillations is 1.2 cm, will the block on
the top slip?

block will not slip?

A 2.20-kg object is attached to a spring and placed on
frictionless, horizontal surface. A horizontal force of 18.0 N is
required to hold the object at rest when it is pulled 0.200 m from
its equilibrium position (the origin of the x axis). The
object is now released from rest from this stretched position, and
it subsequently undergoes simple harmonic oscillations.
