  • question_answer
    A body of mass 3kg is acted on by a force which varies as shown in the graph below The momentum acquired is given by  

    A) Zero

    B) 5 N-s

    C) 30 N-s

    D) 50 N-s

    Correct Answer: D

    Solution :

    [d] momentum acquired = Area of force - time graph \[=\frac{1}{2}\times (2)\times (10)+4\times 10=10+40=50\,N-s\]
