This note is concerned with everyone on brilliant . I have been solving problems in **Mechanics** section which are sometimes ambiguous or their answer is not correct. For an instance , this problem. The answer has been rounded off without informing. There are times when value of acceleration due to gravity isn't mentioned and what u use is different from the one used in answer (it has happened to me with both 10 and 9.8).I even reported the problems but there was no reply from brilliant.
This results in unnecessary decrease in ratings!I request the staff to look into the matter.

TopNewestHi Pankaj, this occurred because the problem creator decided to round off the answer without stating that in the question.

Thanks for reporting problems which are unclear, it helps us to ensure that the content on Brilliant is high quality and useful to other members.

We have fixed this question and awarded you the points and rating changes accordingly. This arose because the problem creator decided to round the answer, without stating that in the question.

We have no control over the values of constants that people use, which is why we encourage them to state these values as necessary. When you see such problems, please report them as "the problem is not clearly stated", and ask the creator to state the value of physical constants that were used.
