Problem: If an electron travels 0.150 m from an electron gun to a TV screen in 9.0 ns,

Part A: What voltage was used to accelerate it? (Note that the voltage you obtain here is lower than actually used in TVs to avoid the necessity of relativistic corrections.)

I don't know how to get that solution. Please help.
