How would I know when both oscillations are present?

Could you explain what that means?

Yes using MATLAB

So using the forces of motion above I get the following graphs. When x1 is put at an initial position of 0.25 and x2 is at 1.25, the first graph is obtained. When x1 is at -0.25 and x2 is at 1.25, the second graph is obtained. Both times the masses are either in phase or antiphase, which is what...

Okay. So the force on block 1 would be the force from spring 1 and 2. so... F1=-k1(x1)+(x2-x1-1)k2 and the force on block 2 would be F2= -k3(x2-1)-(x2-x1-1)K2I tried these equations and they produce the correct angular frequency if both blocks are initially put at 0.25m to the right of...

Thanks for the help. So for spring 2 it should be 1-x2-x1?

For spring 3, I got (1-x2) for its displacement For spring 2, I got (x2-x1) These still don't seem to be right though

Spring 1 is attached to the left side of block1. Then spring 2 connects the right side of 1 and left the side of 2 together. Then spring 3 goes from the right side of block 2 to another wall. I tried to type out the diagram below. Wall k1 block 1 k2 block 2 k3 wall

Homework Statement Two masses (M1 and M2) are connected together by 3 springs. The spring constants are k1, k2, k3. Block 1 is at equilibrium at x=0. Block 2 is at equilibrium at x=1. Determine a function for the force on the blocks. Homework Equations The Attempt at a Solution [/B] Without...

Homework Statement Why does a longer stick fall over slower when pushed? So for example, you have a 3-meter stick and a 1-meter stick. You hold them so they run from the floor toward the ceiling. You let go of each stick and they fall as a tree would. Why does the longer stick fall slower than...

Using radians I get a final answer of 0.0302. How do you know you need to use radians instead of degrees though. I know that the answer seems more reasonable now but in the future how can I tell?

I know that the answer I am getting currently would be in degrees which is incorrect but I can't seem to find a way to solve for dTheta without it encountering that issue. Is there another way to figure out dTheta?

The only value I could think of was to solve dTheta/Theta for dTheta. So the value is really 30*0.05.

My problem is that if I put theta into the cot and solve the relative accuracy of the angle for delta theta and put that into the equation as well, I get a number over 100% which doesn't seem like it is even remotely correct and I just can't think of any other way to go about it.

Homework Statement 2) A student is performing an angry bird experiment in real life. He calculates the range of the projectile by shooting the bird with a 30 degree angle and an initial velocity of v0 = 20 m/s. a) If the relative accuracy of setting the projectile angle is delta theta/theta =...
