The discussion revolves around calculating the acceleration of electrons in an X-ray tube, given their final speed and the distance over which they are accelerated. The problem involves kinematic equations and the initial conditions of motion.
The conversation is ongoing, with participants exploring the implications of different assumptions regarding the initial velocity. Some guidance has been offered regarding the necessity of knowing the initial velocity to solve the problem, but no consensus has been reached on its value.
There is uncertainty about whether the problem statement explicitly indicates the initial velocity, leading to questions about the completeness of the information provided.
You are correct, without knowing v-initial this problem cannot be solved. The problem author problem meant for v-initial to be zero, but that should have been stated or somehow implied in the problem statement. Did you copy the problem exactly as it was given? Or was there an accompanying figure that somehow gave information about the initial velocity?warnexus said:how do I find v initial? I need that so I can find acceleration.
