  • question_answer
    A car moving with a speed of \[30\,\,m{{s}^{-1}}\]takes a U-tum in 5 seconds, without changing its speed. The average acceleration during these 5 sec is

    A) \[12\,\,m{{s}^{-2}}\]   

    B)        \[6\,\,m{{s}^{-2}}\]

    C) \[3\,\,m{{s}^{-2}}\]     

    D)        zero

    Correct Answer: A

    Solution :

    [a] Average acceleration \[\frac{change\text{ }in\text{ }velocity}{~~time\text{ }taken}\] \[=\frac{30-(-30)}{5}\] \[=\frac{60}{5}\] = 12 ms-2
