일반물리학 1 — Motion Along a Straight Line: Problem 28

28 On a dry road, a car with good tires may be able to brake with a constant deceleration of $4.92 \text{ m/s}^2$. (a) How long does such a car, initially traveling at $27.2 \text{ m/s}$, take to stop? (b) How far does it travel in this time? (c) Graph $x$ versus $t$ and $v$ versus $t$ for the deceleration.
