Question

A particle starts from rest. Its acceleration left parenthesis a right parenthesis versus time left parenthesis t right parenthesis is as shown in the figure. The maximum speed of the particle will be

  1. 110 blank m divided by s    
  2. 55 blank m divided by s    
  3. 550 blank m divided by s    
  4. 660 blank m divided by s    

The correct answer is: 55 blank m divided by s


    The area under acceleration time graph gives change in velocity. As acceleration is zero at the end of 11 blank s e c

    i.e. v subscript m a x end subscript equalsArea ofblank increment O A B
    equals fraction numerator 1 over denominator 2 end fraction cross times 11 cross times 10 equals 55 blank m divided by s
