    The distance travelled by a particle starting from rest and moving with an acceleration \[\frac{4}{3}\,m{{s}^{-2}}\],  in the third second is

    A) 6 m                              

    B) 4 m

    C) \[\frac{10}{3}\,m\]                    

    D) \[\frac{19}{3}\,m\]

    Correct Answer: C

    Solution :

    Distance travelled by the particle in nth second, \[{{S}_{nth}}=u+\frac{1}{2}\,a(2n-1)\] Where u is initial speed and a is acceleration of the particle. \[n=3,\,\,u=0,\,\,a=\frac{4}{3}\,m/{{s}^{2}}\] \[\therefore \,\,\,{{S}_{3rd}}=0+\frac{1}{2}\times \frac{4}{3}\times (2\times 3-1)=\frac{10}{3}\,m\]
