This contest is a 30-minute individual competition.
Target: This contest is slightly easier than GBO and is primarily aimed at junior and senior high school students (junior high school physics, basic high school physics). Anyone can participate, including university students and working adults.
OK to use: Use of calculators and scratch paper.
Not allowed: Use of generation AI tools, cheating by referring to textbooks or web searches, consulting with others or sharing solutions.
If cheating is discovered, scores will be invalidated according to the terms of service.
*To prevent correct answers by substituting arbitrary values, the numbers may be intentionally made complex. We strongly recommend using a calculator.

Regarding GWCB001.
Due to an error in updating problem slugs, several problems were presented incorrectly. A discrepancy arose between the intended problems and those actually displayed to participants, compromising the fairness of the contest.

問題4の解答形式について
どちらでも同じになりますが、
「Aさんがこの滑り台を頂点から最下点まで滑り降りる間に、段ボールとローラーの間で発生した総摩擦熱(失われたエネルギー)を A0 としたとき、
(⌊100A0⌋)⋅100
を回答すること。」
こちらでお願いします。
補足 「※このローラー滑り台のローラーは回転しないものとする。」という表示が反映されてません!! 誠に申し訳ありませんでした
