    The velocity of a particle depends upon as \[v=a+bt+c{{t}^{2}}\]; if the velocity is in \[m/\sec \], the unit of \[a\] will be [CPMT 1990]

    A) \[m/\sec \]

    B) \[m/{{\sec }^{2}}\]

    C) \[{{m}^{2}}/\sec \]

    D) \[m/{{\sec }^{3}}\]

    Correct Answer: A

    Solution :

    Quantities of similar dimensions can be added or subtracted so unit of a will be same as that of velocity.
