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.
