The length of second's hand in watch is 1 cm. The change in velocity of its tip in 15 seconds is

  1. Zero    
  2. fraction numerator pi over denominator 30 square root of 2 end fraction c m divided by s e c    
  3. fraction numerator pi over denominator 30 end fraction c m divided by s e c    
  4. fraction numerator fraction numerator pi square root of 2 over denominator 30 end fraction c m over denominator s e c end fraction    

The correct answer is: fraction numerator fraction numerator pi square root of 2 over denominator 30 end fraction c m over denominator s e c end fraction


    capital delta v equals 2 v sin invisible function application open parentheses fraction numerator 90 degree over denominator 2 end fraction close parentheses equals 2 v sin invisible function application 4 5 degree equals 2 v cross times fraction numerator 1 over denominator square root of 2 end fraction equals square root of 2 v
    equals square root of 2 cross times r omega equals square root of 2 cross times 1 cross times fraction numerator 2 pi over denominator 60 end fraction equals fraction numerator square root of 2 pi over denominator apostrophe 30 end fraction   c m rightwards arrow over short leftwards arrow divided by rightwards arrow over short leftwards arrow s
