    A train moves from one station to another in 2 hours time. Its speed-time graph during this motion is shown below. The maximum acceleration during the journey is:

    A)  \[140\,km{{h}^{-2}}\]    

    B)         \[160\,km{{h}^{-2}}\]   

    C)  \[100\,km{{h}^{-2}}\]                   

    D)         \[120\,km{{h}^{-2}}\]

    E)  \[150\,km{{h}^{-2}}\]

    Correct Answer: B

    Solution :

    Maximum acceleration = max slope (CD) \[=\frac{DL}{CL}=\frac{60-20}{1-0.75}=160\,km/{{h}^{2}}\]
