  • question_answer
    A particle moving with a uniform acceleration travels 24 m and 64 m in the first two consecutive intervals of 4 sec each. Its initial velocity is                                 [MP PET 1995]

    A)          1 m/sec        

    B)             \[10\,m/\sec \]

    C)             5 m/sec

    D)                         2 m/sec

    Correct Answer: A

    Solution :

                     Distance travelled in 4 sec             \[24=4u+\frac{1}{2}a\times 16\]                  ?(i)             Distance travelled in total 8 sec             \[88=8u+\frac{1}{2}a\times 64\]                  ?(ii)             After solving (i) and (ii), we get \[u=1\]m/s.
