SUMMARY
The discussion focuses on solving for the time variable \( t \) in the equation \( x = 16te^{-t} \), which describes the position of an electron along the x-axis. The derivative \( x' \) is calculated as \( x' = e^{-t} - te^{-t} \). Setting \( x' = 0 \) leads to the equation \( -te^{-t} = -e^{-t} \), resulting in \( t = 1 \) as the moment when the electron momentarily stops. This solution confirms that the electron is at a distance of \( x(1) = 16 \) meters from the origin when it stops.
