Solving Relative Velocity Problems: 346 vs 350

Click For Summary
SUMMARY

The forum discussion revolves around solving a relative velocity problem where the calculated answer was 346, while the correct answer is 350. The user initially questioned if the discrepancy was due to rounding. Another participant clarified that while rounding was involved, the user's method was incorrect. The correct approach involves using the formula |v| = √((300 + 60cos40)² + (60sin40)²), which led to a recalculated answer of 348, prompting further inquiry into its accuracy.

The Attempt at a Solution



I got the answer 346, the real answer was 350. Did they just round up?

Thanks :)
They rounded up a little, but your answer's not really correct.

This is the way I did it this time. I got 348. Does that seem correct?
