Two springs with a spring constant of k = 6430 N/m are joined and connected to a block of mass 0.245 kg. The system is then set oscillating over a frictionless surface. What is the frequency of the oscillations? This is what I think is the correct approach to this question: since the...

How do you apply Hooke's law to particles joined to multiple springs. For example in the diagram below: 0rigin |-\/\/\/\/- P1 - /\/\/\/\- P2 -/\/\/\/\/\/-| I mean, would you have to introduce a new variable to indicate displacement if you altered one of the springs? Also, suppose the...

Hello, I have a question regarding the conservation of energy. So you have a long spring (the kind that wants to stay closed, as in when you pull on it, it reacts in the opposite direction) situated in a vertical position. You attach the weight to the bottom of the spring, and let it bounce...

The system examined in the problem is depicted below: ^^^^^(m1)^^^^^(m2) m1 and m2 are connected by a spring and m1 is connected to the wall by a spring. The spring constant is k. T = m/2 [ x1'^2 +x2'^2 ] kinetic energy of system (x1' is velocity of m1, x2' is velocity of m2) U = 1/2 m...

I will make a crude visualization of this system: |-------------O--------------| <-----a------><------a------> Identical springs: k1=k2=k Natural Length: l > a The problem is to prove that the system is unstable. Obviously, a slight movement directed off the horizontal axis will cause the...

A 0.164-kg block is dropped straight downwards onto a vertical spring. The spring constant of the spring is 62 N/m. The block sticks to the spring and the spring compresses 0.17 m before coming to a momentary halt. What is the speed of the block just before it hits the spring? Give your...

*sigh* I'm SURE there is a perfectly reasonable solution to this problem, unfortunately for me it remains just beyond the next horizon. :cry: The green block (2 kg) is falling at a speed of 29. m/s and is 3.0 meters above the spring. The spring constant is 4.00E3 N/m. What is the maximum...

A mass m is attached to a massless rod of length L to make a pendulum. In addition, when the rod is vertical, two relaxed springs with constants k1 and k2 are attached on either side of the mass to walls. What is the period of oscillation. I started by writing the potential energy as a...

My physics class is intro more or less (it's calc based; 111 NOT 101). I'm a bit confused when it comes to springs..specifically, finding the maximum compression a spring will have. Here are the given variables in a problem in my textbook: *spring has negligible mass *force constant(k) =...

i have been given the following problem from everyone's favorite, mastering physics. "The Great Sandini is a circus performer with mass 60.0 kg who is shot from a cannon (actually a spring gun). You don't find many men of his caliber, so you help him design a new gun. This new gun has a very...

Just to start with this equation: \frac{1}{6} m_s v^2 Incase my latex is broken, its (1/6)(m_s)(v^2). Where m_s is the mass of the spring, and V is the velocity of the spring at it's tip. I'm looking for a derivation for this equation, because it was just handed to me and I don't like using...

hi i have this problem that i have to solve involving a spring and a mass attached to it and damping of the spring. i will first in this first post like put down the problem, and then in further posts i will put down how i am going with the problem, eg like what i have got etc, and um well any...

Why is it that a spring exerts a force -kx on a block? Is it because the atoms making the spring themselves are in a stable equilibrium when the spring is at its relaxed lenght, but as soon as it is stretched, for small displacement around the equilibrium position, a "locally hookian"...

Well I am working on a lab report for 12th grade physics and my teacher has decided to throw a cuve ball at us. The lab is designed to determine the value of the force constant of a spring by measuring the number of oscillations a certain weight makes when on the end of the spring. To find k was...

a physics question i was assigned was: If two springs are made of the exact same material, but one is shorter than the other, why is the shorter spring stiffer than the other spring? I know it is related to Hooke's law being that if a spring has a higher K value, it is stiffer, but I don't...
