Find the motion of an object subject to a linear restoring force
and a linear retarding force when it starts from equilibrium at
initial velocity v0. Consider underdamped, critically damped, and
overdamped cases.
An object with mass 0.190 kg is acted on by an elastic restoring
force with force constant 10.3 N/m. The object is set into
oscillation with an initial potential energy of 0.150 J and an
initial kinetic energy of 6.90×10−2 J.

An object with mass 0.150 kg is acted on by an elastic restoring
force with force constant 11.0 N/m . The object is set into
oscillation with an initial potential energy of 0.130 J and an
initial kinetic energy of 5.10×10−2 J .
1. What is the amplitude of oscillation?
2. What is the potential energy when the displacement is
one-half the amplitude?
3. At what displacement are the kinetic and potential energies
equal?
4. What is the value of...
Generally speaking, a system undergoes simple harmonic motion if
there is a restoring force that increases linearly with
displacement from equilibrium. In the discussion, describe how a
pendulum and a mass on a horizontal spring satisfy those conditions
(ignore any friction forces); also, include another example of a
real world system that undergoes simple harmonic motion and discuss
how it satisfies the conditions mentioned above. Finally, be sure
to respond to at least two of your peers’ discussion posts.
Consider the following descriptions of the vertical motion of an
object subject only to the acceleration due to gravity. (Note: the
acceleration due to gravity is 9.8 m divided by s squared.) a.
Find the velocity of the object for all relevant times. b. Find the
position of the object for all relevant times. c. Find the time
when the object reaches its highest point (What is the height?)
d. Find the time when the object strikes the ground. A...
5. For an object moving in uniform circular motion, does the
centripetal force do work on the object?
A.
No, because the force is always perpendicular to the object's
displacement.
B.
No, because the displacement of the object is zero.
C.
Yes, because the object is moving.
D.
Yes, because work is force times distance and the object is
moving from the force.
6. How can two collisions have the same change in momentum even
though one collision took longer...
1)An object experiences a force in the direction opposite its
motion. This means
the work vector points in the negative direction
the scalar value of work is negative
the scalar vector of work could be either positive or negative,
depending on which direction is chosen to be positive.
the work vector could point in either the positive or negative
direction, depending on which direction is chosen to be
positive.

Vivian and Noelle are traveling in opposite directions from their starting point. Noelle is traveling 5mph faster than Vivian. given that the distance between them after 8 hours is 136 miles, determine the velocity of each one of them
consider a linearly damped simple harmonic oscillator
with mass m,restoring force contsant k and resistive force constant
c.if c >sqrt(4mk), work out the expression for the displacement
as a function of time and describe the predicted time dependence of
the motion.
Besides the gravitational force, a 2.50-kg object is subjected
to one other constant force. The object starts from rest and in
1.20 s experiences a displacement of (5.40î − 3.30ĵ) m, where the
direction of ĵ is the upward vertical direction. Determine the
other force.
