Question

A particle starts from rest at t equals 0 and moves in a straight line with an acceleration as shown below. The velocity of the particle at t equals 3 s blankis

  1. 2 blank m s to the power of negative 1 end exponent    
  2. 4 blank m s to the power of negative 1 end exponent    
  3. 6 blank m s to the power of negative 1 end exponent    
  4. 8 blank m s to the power of negative 1 end exponent    

The correct answer is: 4 blank m s to the power of negative 1 end exponent


    Velocity of graph equals Area ofblank a-t graph
    equals open parentheses 4 cross times 1.5 close parentheses minus open parentheses 2 cross times 1 close parentheses equals 4 m divided by s
