Question

The velocity-time graph of a particle in linear motion is shown. Both v and t are in SI units. What is the displacement of the particle from the origin after 8 s?

  1. 6m  
  2. 8m  
  3. 16m  
  4. 18m  

The correct answer is: 6m


    Displacement = Area of upper trapezium- Area of lower trapezium
    equals fraction numerator 1 over denominator 2 end fraction open parentheses 2 plus 4 close parentheses cross times 4 minus fraction numerator 1 over denominator 2 end fraction open parentheses 2 plus 4 close parentheses 2 equals 12 minus 6 equals 6m
