Particle Speed And Acceleration ?

AI Thread Summary
To calculate the speed of a charged particle in a vacuum tube with applied voltage, energy conservation can be used. However, acceleration cannot be determined without knowing the length of the tube, as it is dependent on that variable. Kinematic equations provide the necessary tools to find acceleration once the tube length is known. The discussion emphasizes the importance of understanding both energy conservation and kinematic principles in this context. Overall, the conversation highlights the need for clarity in applying physics concepts to specific scenarios.

Hallo Physics Forum

I have a question, if you have a particle( a charged particle ) in a vacuum tube with applied voltage
then how can you calculate the speed and acceleration it will get in the tube when there's applied voltage to the tube

You can calculate its final speed (just use energy conservation), but not its acceleration which depends on the length of the tube.

If you or anyone knows have to calculate the acceleration in a tube with length x
It whould be very usefull

Did you even look at the link I gave you? You have all the kinematical equations that you need to find the acceleration!

Oh sorry.
Thanks for the help. It helped alot
 
Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds?

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
