Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

And what if you are recruited in a calculus/physics lab for coding ?
I'm using codewars to learn programming languages and development techniques, not mathematics. This would be a better problem if it gave more emphasis on the actual coding requirements than on knowing calculus / physics. More hints for the formula needed in the Speed portion would improve this greatly.
