Okay...so I have Physics homework due at midnight, 8 hours. And I'm stuck on a few problems...posting here for some help.
An explanation of how to do it would be much more appreciated then just answer.
1a)A 1816 g mass is on a horizontal surface with μk = 0.48, and is in contact with a...
Could someone please point me in the right direction for finding formulas dealing with torsion springs and also understanding more about how they work?
Thanks Carla
Hi, I need to know where I can find information on the web so as to analytically solve the system on the attached jpg where:
m1, m2 are the values of each mass
v1, v2 are the speeds of each mass
K1, K2 are the stiffness coefficient of each spring
L1, L2 are the lenghts of each spring...
Please feel free to ask me questions if anything doesn't make sense.
I have this problem that's driving me crazy. The system I'm looking at is a 2 mass, 3 spring system configured like this,

A mass m is connected to two springs, with spring constants k1 and k2. (m connected to k2, which is connected to k1 which is connected to a wall horizontally).
Show that the period for the configuration is given by
T = 2 \pi \sqrt{m ( k^{-1}_1 + k^{-1}_2)}
Well I know .5kA^2 = .5mv^2...
There is a spring on a ledge that is 15 m above the ground. It is compressed 0.5 m by a block of 3 kg, and its spring constant is 15 N/m. I'm not certain of the exact wording, but somehow the compressed string (with the block) is the horizontal length of the ledge.
Now in this scenario, the...
hi, I was going through my homework and i came to a problem that i can't seem to get.
Consider the mass attached to four identical spring. Each spring has the force constant k and unstreched length L_0, and the length of each spring when the mass is at the origin is a(not necessarily the same...
This is my first post...and I hope I am doing this correctly...I know this isn't a place to "get my homework done for me". I just want to know how to do it.
3. [HRW6 7.P.022.] A 220 g block is dropped onto a relaxed vertical spring that has a spring constant of k = 2.8 N/cm. The block...
I am in grade 12 physics, and i have to practice equation proofs. I am currently studying work, kinetic energy, springs, and potential energy (gravity and elastic).
Does anyone have a good proof?
You are given an 8.00 kg box resting on a spring. The spring is compressed 7.0 cm by the box.
(a) What is the spring constant? ____ N/cm
(b) The box is pushed down an additional 30.0 cm and released. What is the elastic potential energy of the compressed spring just before that...
Here is the situation: There is a spring connected to a wall at one end and a mass m1 at the other, which in turn is connected to another spring, which is connected to mass m2, which is connected to another spring which is connected to another wall. In other words:
Wall ----- m1 ----- m2...
suppose that the two springs have different spring constants k1=280 N/m and k2=260 N/m and the mass of the object is m=14 kg. Find the frequency of oscillation of the block in Hz.

the first picture on this site is what the...
Figure 1 shows a mass m in equilibrium between two stretched helical springs on a smooth horizontal surface. k_1 and k_2 are the force constants of the springs and e_1 , e_2 are their respective equilibrium extensions.
The mass m is displaced X to one side ( X is smaller than e_1 and e_2 )...
I have the following problem on which I am unsure how to proceed.
A spring with a spring constant K = 20 N/m is shown below. It is stretched 1 cm from its equilibrium position when a current I passes through the wire. How big is the current in the wire?
The magnetic field is coming out...
I've been having troubles figuring out this question, because the cart is not actually attached to either spring nor always touching one. Any help would be appreciated.
A cart moves without friction between two springs, back and forth. Both springs have a spring contact of D = 72 N/m. At...
ok, I've been at this for quite some time. its pretty difficult for me and need some help fast.
The question is
A 2kg box lies at rest on an incline of 30 degrees with a friction of .2 . The box slides down, and compresses a spring of k=10n/m. What is amount of forces that shoots up the box...
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...
Physics is my first class so I'm almost never awake. Could someone please tell me what the variables stand for.
Spring: T= 2 * pi * square root (m/k)
What is T, m, k?
Hooke's Law: F = -Kx
What is K, x?
Pendulums: T = 2 *pi* square root (l/g)
What is T, l, g?
Centrifical Force:

The ramp and the ledge which the box sits on is has a Mu(k) of 0... the spring compression of the block when released from rest is 98cm... i found the height of the ramp being 29m, and the speed at the top of the ramp being 11.8.. i just need help...
How do i find the force constant of a spring with a Newton meter?
Do i graph the force applied vs. distance of stretch? What is on the x-axis, what is on the y-axis?
How do i find an equation for the amount of skretch needed for on spring on a projectile, with the horizontal distance, angle...
I have two homework problems that I'm really stuck on. Can someone please help me out? Thanks!
1) A 0.55-kg block is hung from and stretches a spring that is attached to the ceiling. A second block is attached to the first one, and the amount that the spring stretches from its unstretched...
Someone please help me how to do these problems below. Thanks a lot for your help.
1) On the surface of the moon the acceleration due to gravity is approximately 1/6 the sun at the surface of the earth, and on the surface of the sun it is approximately 29 times as great as at the surface of the...
I drew out a diagram for this question and wrote out all my givens. I looked through all the formula's I have and I just can't put the pieces of the puzzle together. If anyone can help that would be greatly appreciated.

A 1.5kg steel mass is dropped onto a vertical compression...
Two springs are in series. You know the constants for each individual spring. How do you find the spring constant for the spring system?
|-OOOOO---o---OOOOOOOOOO-| --->F
In the middle of the spring system (where the "o" is) the net force is zero and we have
k1x1=k2x2 disregarding sign...
if p is momentum then dp/dt = f right?
I've heard that dp/dt can be written as f = m(dv/dt) + v(dm/dt)
Can someone tell me what this actually means, because it would seem that m would be dependent on v and v dependent on m, so I am not sure how this would work out.
Also, can someone...
