일반물리학 1 — Motion Along a Straight Line: Problem 35

35 In a particle accelerator, an electron enters a region in which it accelerates uniformly in a straight line from a speed of \(4.00 \times 10^5 \text{ m/s}\) to a speed of \(6.00 \times 10^7 \text{ m/s}\) in a distance of \(3.00 \text{ cm}\). For what time interval does the electron accelerate?
