Homework Statement
A train enters a curved horizontal section of track at 100 km/hr and slows down with constant deceleration to 15 km/hr in 12 seconds. An accelerometer mounted inside the train measures a horizontal acceleration of 2 m/s^2 when the train is 6 seconds into the curve. Calculate...
I don't know if I should post this in this forum..(Please tell if this out of its domain)
We are carrying out different experiments in a cubical room.
1.On adjacent (perpendicular) walls we have, for the first expt., two identical balls touching the floor which are shot towards each other...
mgb_phys,
Whatever you meant by that last line but I had never seen that icar101 thing & I have no way to prove. But I am happy that my question's answered & as I had thought it can fly (just that it's goin to satisfy much more than a poor man's desire for adventure).
This may be a bit weird but please consider my idea..
Flying Machines like the aeroplane work on the principles of aerodynamic lift employing a special wing structure.
What if I make an alteration to this design such that these "wings" are replaced by moveable "curved surfaces" like the...
tiny-tim,
I get the fact that if the bike would have behaved like the car then it would fall over. But even the biker is in a rotating frame. So he too would experience a centrifugal force. Further if I make a bike with extra wide wheels (it's still a bike, it still has one row of wheels, just...
Well, I don't want the solution but a few ideas to start solving this..
Two unstable particles move in the reference frame M with a velocity v=0.992c. The distance between them in this reference frame is l=110 m. At a certain moment both particles decay simultaneously in this frame. What...
Hi there!
When I had first learned about the situation of a vehicle taking a turn around a bend, I was quick to conclude that the vehicle would bend inwards (towards the center of the circular path) as I had the image of the MotoGP racers who bend to the extremes to negotiate sharp bends. But...
Can someone help me out with this problem(not homework ofcourse)..
Find the threshold energy of gamma quantum required to form
- an electron-positron pair in the field of a stationary electron;
- a pair of pions of opposite signs in the field of a stationary proton..
Thank you for reading
Dont know if this has been discussed here before..
If two relativistic particles are traveling with speeds 'u' &'v' ,how to calculate the relative velocity?
Sorry for the long silence.I couldn't get near the comp yesterday due to certain reasons.but I am interested to learn about the derivation..
(This may not be relevant but I am finding all the sections given in the LaTex patterns very blurred and difficult to read. Is it just my machine or do...
Hi!
A little food for thought for people who like high school physics labs..
In a standard rheostat(I have seen only the cylindrical one..the question is about rheostats of this shape..), we find a metal wire wound over a cylindrical core. The wire is wound with very closely spaced turns...
Actually this may come out as a derivative of the original question.I want to ask the mentor on the lines of the comment made: What are these "certain special cases of high symmetry" where I can use the c.o.m. concept as I had used in my query??
Hoping for a quick reply..
No, this isn't homework (it wouldn't be very fair to expect a member to violate rules from day 1).I have read all your rules and I would perfectly abide by those. Actually I have asked this to many people and received replies which don't really satisfy me. Thank You all for your efforts but I...
Hello astro2cosmos,
First of all, you have made a mistake in calling it the 2nd law, it is actually the 1st law..
You didnt mention if you consider these two events(moving two objects through a distance) independent ?
If you are an independence lover,then the answer would depend on the...
