1. The problem statement, all variables and given/known data There is a grasshopper who wants to cross a log(cylindrical) of radius $$R$$.Calculate the minimum velocity required by grasshopper to just scrape the log. 2. Relevant equations First of all I have a doubt.So equations are out of question. At least I know that it is a question of projectile motion. 3. The attempt at a solution I have a doubt.For minimum velocity should the grasshopper scrape once or twice over the log?Please someone clarify it.
