The discussion centers on a mechanics homework problem where the weight was incorrectly stated as 18 kg instead of the correct 8 kg. The user was advised to redo the arithmetic in the final step of solving for velocity (v) to ensure accuracy. Additionally, a suggestion was made to avoid premature rounding during calculations to maintain precision. Overall, the solution was deemed acceptable aside from these adjustments.

Yes, it looks fine. My only suggestion is that you be careful about rounding off too soon.coffeem said:does the rest of it look ok?
