    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 :

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