아버지와 캠핑을 간 라임은 어쩌다 감자구이 보조가 되었다.
그래서 빠르게 감자를 익혀야 하는데, 라임은 사실을 하나 알아냈다.
감자가 완벽한 구라고 가정하면, 불과 가장 가까운쪽부터 익기 시작하며,
감자의 반지름이 rcm라고 가정했을 때 (r/16)m/s2의 가속도로
지름을 축으로 하여 그 지점에서 수직인 모든 원 구간이 익고,
감자의 중심으로부터 지름의 25%안에 해당하는 모든 구간에서는 익는 속도가 40% 감소한다.
이때, 라임이 지름 10cm 감자를 하나 굽는데 걸리는 시간은?
(-프사를 준 원파에게 감사하다는 말을 전합니다)
