SUMMARY

The discussion revolves around calculating the y component of an electron's velocity as it impacts a detection screen after being shot at an initial speed of 4.14 × 106 m/s at an angle of 43.6° in a uniform electric field of 5.34 N/C. The participants break down the initial velocity into x and y components, determining the x component to be approximately 2.998 × 106 m/s and the y component to be approximately 2.855 × 106 m/s. They also calculate the time taken to reach the screen as approximately 5.47 × 10-7 seconds and derive the acceleration due to the electric field, concluding that the y component of the electron's velocity at impact is approximately 2.34137 × 106 m/s.

I think that's about right.

ok the numerical value is correct but the units are still wrong! lol

You're now answering a question regarding velocity, not position so it has different units than the last time you asked about units.

* face palm * I need to stop doing homework so late, I got it now. Thank you soooo much for your help and time. I really appreciate it! This will certainly be a question I'll review for an upcoming exam :smile:

You're welcome.

Time for me to get some sleep too.
