1) An evacuated tube uses an accelerating voltage of 44 kV to accelerate electrons to hit a copper plate and produce X-rays. Ignoring relativistic effects, what would be the maximum speed of these electrons?

2) A battery-operated car uses a 12.0-V system. Find the charge the batteries must be able to move in order to accelerate the 600 kg car from rest to 30.0 m/s.

3) I want to accelerate an electron to the speed of sound (343 m/s) by electrostatic force alone. To do so I’ve devised a way to store as much charge as I’d like at a single fixed point which will be located 0.35 m from the electron. How much charge do I need to accumulate to accomplish my goal?
