Hmm well with the vertical thing I've tried it a few times and it seems that the sticks do break. I don't really understand what you mean about rotational motion though, if you think it will help for my project please explain.
I was thinking that I need the structure to be very long and have...
For a school project I have to build a device made of only toothpicks and glue gun glue that will hold an egg. The device will be dropped 5 meters and the egg must not break, so the idea is to build a device with a good crumple zone. I have a few ideas about how to build it but its pretty hard...
Hi I am trying to simulate a car crash scenario mathematically and come up with reasonable numbers for a project. The problem is I do the calculations and everything seems mathematically correct but the numbers seem weird.
I simulated an 80 kg passanger in a car crash that was going 20 m/s...
k... So my other one was wrong then. I did this and got (p1/p2)=v2/v1 and since v2 will be less then v1 this means that p2 is larger right? Bah I am getting so confused by such a small question, I did fine with all the ones with actual data but this one is confusing me.
Ok I am trying to figure out what you mean by writing the equations in terms of m and v. After playing around with the algebra for a while i got that P1=(P2V2)/V1 But i can't figure out what use this is. (2 is the larger truck 1 is the smaller one, I assume when it says smaller it references...
Hello I'm stuck on two momentum concept problems and can't figure them out, I was hoping someone could provide help.
1.A small truck and a large truck have the same kinetic energies, which truck has the greater momentum? Justify your answer.
Well i know Ek=.5mv^2 and that momentum p=mv...
As you may have noticed I've got a bit of a rollercoaster theme going.
My problem now is i have an 800 kg cart and I need to calculate the work done by bringing it to the top of the rollercoaster. The slope of the lift is 20 degrees and the maximum height is 30 m. From this i calculated the...
Nate that is what I am supposed to find, the Average force of friction. But I don't know what to do because don't i need a distance to use the equation W=F x d to solve for F?
I do have the times but i can not figure out how to encorporate them to find the average force of friction.
I am doing a project and one of the questions is to find the average force lost to friction. We measured a ball going down a "roller coaster" (it had 2 humps on it). WE have all the speeds and distances and accelerations, Now i calculated the energy lost to friction by taking the initial...
Do you mean W=Fxd ? If I used that i would already have W and I would be solving for F right, ok sweet I think I'm almost there now but I can't think of a way to calculate d, because it is a rollercoaster path, so its all curved and such. Maybe if i averaged the velocitys over that time and...
brewnog thanks for that, I had already found out the amount of energy lost to friction for the two point. To do that i subtracted the actual kinetic energy and the gravitational energy from the initial gravitational energy, which will give me the amount of energy lost to friction. However this...
Question: Determine the average force of friction over the first drop and over the entire trip from top to bottom.
This is a question of have from a lab experment which was when we designed a "roller coaster" for a ball (it was a downwards ramps with 2 humps on it). I have the actual...
For school I have to explain how whiplash can occur if a driver is at a read light and he seat doesn't support his head, and he gets hit from behind. Now I was thinking that I needed to find the velocity of the car after it had been hit from behind, so that I could find the corce acting on the...
After thinking about what you said about the air bag I decided to change my size down to .3m^2 which to me seems more reasonable. I don't know what to do about the pressure injury aspect of this problem though, the exact problem says explain how airbags minimize injury during a head on...
