Homework Statement
So I just wrote my midterm in physics, and I was curious on how to do the last question.
Parallel plates, length 5.5cm,
Distance between them is 0.3 cm
Electric Field (E) is 5.4x10^4
Asking what is the initial speed of a proton going through the parallel plates if it just...
No problem. Happy to help. Just 1 thing though, you learn integrals in university or college, so you don't need to bother with learning them now. You could if you want, but it would be a lot of extra work.
I am unsure as to if you have learned how to do derivatives yet. But that is the easiest way of solving this. The derivative of displacement is velocity, and the derivative of velocity is acceleration. Have you by any chance learned derivatives yet?
I will explain using the derivative.

Two loudspeakers emit sound waves along the x-axis. a listener in front of both speakers hears a maximum sound intensity when speaker 2 is at the origin and speaker 1 is at x=0.50m. If speaker 1 is slowly moved forward, the sound intensity decreases and then increases...

A wave travels along a spring at speed v0. What will be the speed if the string is replaced by one made of the same material and under the same tension but having twice the radius.
Answer in book says (v0/2)

I was working on a problem in my book, and I didn't know how to answer the question. So I looked at the solution manual. and it had this

I do not know where the (cosx + 1) on the bottom came from. Any ideas? Please explain.

I asked my prof about the cart question, and he said the answer was no, which is what I put.
Didn't ask him about the other question, but a lot of people here are saying that it would have the same speed.
This isn't a homework question, just did a midterm and I am curious about a question. it had this diagram. Same initial speed.

and it asked which statement is most correct about the speed at height, h (the line going across the graph)
a) It depends on their masses
b)...
