Question

The variation of velocity of a particle moving along a straight line is shown in the figure. The distance travelled by the particle in 4s is

  1. 25 m    
  2. 30 m    
  3. 55 m    
  4. 60 m    

The correct answer is: 55 m


    S equals fraction numerator 1 over denominator 2 end fraction cross times 1 cross times 20 plus 1 cross times 20 plus fraction numerator 1 over denominator 2 end fraction cross times open parentheses 20 plus 10 close parentheses cross times 1 plus 1 cross times 10
    equals 55m
