    A body is moved in straight line by constant power of machine. What will be the relation the travelling distance and time?

    A)  \[{{s}^{2}}\alpha \,{{t}^{3}}\]             

    B)  \[{{s}^{2}}\alpha \,{{t}^{3}}\]

    C)  \[{{s}^{3}}\alpha \,{{t}^{2}}\]          

    D)  \[s\,\alpha \,{{t}^{3}}\]

    Correct Answer: A

    Solution :

     Power\[=[M{{L}^{2}}{{T}^{-3}}]=\]constant \[\therefore \] \[\left[ \frac{M{{L}^{2}}}{{{T}^{3}}} \right]=\]constant \[\therefore \] \[[{{L}^{2}}]\propto [{{T}^{3}}]\] or           \[{{S}^{2}}\propto {{t}^{3}}\]
