i challenge anyone to answer this physics problem!!!?

Posted on May 6, 2012 by admin| 1 Comment

A spring of negligible mass stretches 3.00 cm from its relaxed length when a force of 6.10 N is applied. A 1.100-kg particle rests on a frictionless horizontal surface and is attached to the free end of the spring. The particle is pulled horizontally so that it stretches the spring 5.00 cm and is then released from rest at t = 0.

(a) What is the force constant of the spring?
N/m
(b) What are the period, frequency, and angular frequency () of the motion?
s (period)
Hz (frequency)
rad/s ()
(c) What is the total energy of the system?
J
(d) What is the amplitude of the motion?
m
(e) What are the maximum velocity and the maximum acceleration of the particle.
m/s (maximum velocity)
m/s2 (maximum acceleration)
(f) Determine the displacement, x, of the particle from the equilibrium position at t = 0.500 s.
m

Particle C and particle D are held together with a compressed ..?

Posted on April 27, 2012 by admin| 5 Comments

Particle C and particle D are held together with a compressed spring between them. When they are released, the spring pushes them apart and they then fly off in opposite directions, free of the spring. The mass of C is 2.0 times the mass of D, and the energy stored in the spring was 60J. Assume that the spring has negligible mass and that all its stored energy is transferred to the particles. Once that transfer is complete, what are the kinetic energies of (a) particle C and (b) particle D?
explain your answer pleas.

energy from dead weight.?

Posted on December 31, 2011 by admin| 3 Comments

energy is stored in any object. releasing it can be the trick. now if 500 lbs of lead is pressing against a spring that is just keeping lead from touching the ground, the spring is exsorting energy keeping the weight up. The energy in the spring can and should be able to be measured, as some type of heat, or measure the atoms that are being compressed. even if you could collect any energy from such a experiment you could use it for switching something Electrical or as a signal. it is energy. correct? it should be also free. Incress the weight, more energy. thanks for all input. Dave
Can I use this energy for any purpuse?. And once the weight is on the spring and it remains stable, thats what I want to use. it should remain usable for a long time, and using the right matereal it should last forever, being Relative.
and again, sorry, do you think that there is any energy In between the coils?
I think, that there maybe energy in between the coils. I just need to find a way to measure it. Maybe it has been tried, if so I would like to know, if not is anyone ever tried to measure such a test.?

Spring problem for physics!?

Posted on December 22, 2011 by admin| 3 Comments

A spring of negligible mass has force constant k = 1600 N/m.

How far must the spring be compressed for an amount 3.10 J of potential energy to be stored in it?

You place the spring vertically with one end on the floor. You then drop a book of mass 1.10 kg onto it from a height of 0.900 m above the top of the spring. Find the maximum distance the spring will be compressed.
Take the free fall acceleration to be g = 9.80 m/s^2.

    Please help me finish physics problem!!!?

    A spring of negligible mass stretches 3.00 cm from its relaxed length when a force of 6.40 N is applied. A 0.300 kg particle rests on a frictionless horizontal surface and is attached to the free end of the spring. The particle is pulled horizontally so that it stretches the spring 5.00 cm and is then released from rest at t = 0.
    (a) What is the force constant of the spring?
    _213.3_ N/m

    (b) What are the angular frequency, the frequency, and the period of the motion?
    _26.67_ rad/s
    _4.244_ Hz
    _.2357_ s

    (c) What is the total energy of the system?
    _.2666_ J
    (d) What is the amplitude of the motion?
    _5.00_ cm

    (e) What are the maximum velocity and the maximum acceleration of the particle?
    max velocity ___ m/s
    max acceleration ___ m/s

    (f) Determine the displacement, x, of the particle from the equilibrium position at t = 0.500 s.
    ___ cm

    I got 6 answers correct, but somehow I cannot get the last 3. Will you please show me the steps as well? Thanks!
    Thank you catarthu…
    Both the answers for velocity and acceleration are correct. The only answer that is not working is the displacement one. Do you know where any error can be from? Thanks again! :)
    The displacement turned out to be 3.59 cm.
