You can model vibrations using a spring and a damper. If you call the building your mass, take the spring as your foundation or steel memebrs, use the ground or air as your damper and your forcing function on the RHS would be a trigonometric function such as sin or cos. In order to get a...
The question strictly states that the motion should be modeled by ODE's and that linear momentum cannot be used (even though in hinsight they are the same).
Either way, I found out that the one spring system can be used, but only to model the CM of each vehicle. It cannot be used to...
Good day all,
I've got a rather puzzeling question on hand that is part of my Dynamic project. I need to model the collision of two vehicles. Each vehicle is traveling head on to the other, and each one has a spring attached to its front. We can assume that the final velovity after collision...
The reason the bike does not tip over when moving is because of a gyroscopic property called precession. When the bike is not moving, any lateral force on the bike tire creates a torque about the centre. This torque makes the bike tip. Once the bike is moving, this torque is still there, but...
Magnitude of displacement is distance, with a unit of meters. It still has a unit of meters but it does not have a direction. If the magnitude is 1, this does NOT mean that in one second the distance traveled is 1. You are thinking about speed of 1m/s.
No, the magnitude of displacement cannot...
I read somewhere that the optimum way for space travellers to travel would be to use general relativity to its best, and vreate a gravitational well, so to speak, or to bent the spacetime in front of their desided direction, thus causing them to be pulled in and creating motion. The article...
yes, this will give you the density, just rememner that you need to find density in grams per cm^3 or kg per m^3. You need to make sure you convert from volume of water to the metric system. 1000L = 1m^3.

Well, why would only large events such as novas and black holes be the only source for gravity waves. There is no actual theoretical way that physicists can manipulate spacetime yet?
We are not here to solve arbitrary problems, if you want to know how to approach th problem, draw the free body diagram, label all of your axis, create your force equations and work form there. Try doing this first, if you get stuck, come and ask.

No its not what you said, you can have an average speed of any number while having the average velocity be 0. Imagine a car traveling in an oval course, the displacement is 0, but the distance traveled is the length of the track. Now tell me, is the magnitude of the average velocity equal to the...
Thats a lot of questions to answer, General Relarivity and when dealing with gravity, the earth cannot be taken as a particle.
Your first statement is incorrect, velocity is displacement over time, your second statement is correct, average velocity is not related to average speed.
Correct...
well, I dont see how you could handle fluid dynamics, fluid mechanics and heat transfer without partial differentials. I would stongly suggest you take the course.

Im assuming it is, but you might be right, since it is a rocket, acceleration might vary, but I doubt it since no mass is lost. Its not a momentum problem where they give you the mass flow rate out, I think its a simple kinematics problem, thats why I assumed constant acceleration.

To answer your second question, I think its because of the sticks shape. Due to the non uniformity of the stick, the centre of mass is not at the exact middle of the shaft, also, becuase of this, when the stick rotates on the ice about its centre of mass, it will have different frictional forces...
This series converges absolutely by the p-series test. I dont see why you have to look for any limits or to check it is decreases. If it comverges absolutely, then it converges.

You draw your free body diagram, you will see that the force you need to move the object will need to overcome the friction force. So the same approach is taken as in the first case, the force you need to move the 1kg object the distance is a little bit more than your friction force, as in the...
I would assume that his average velocity is 0, since it takes him an infinite time to reach the lettuce. As for instantaneous velocity, lower limit would be 0, upper limit I am not sure of, I think it would be highest on the first hop towards the lettuce.
