    The velocity of a particle at an instant is 10 m/s. After 3 s its velocity will become 16 m/s. The velocity at 2 s, before the given instant will be:

    A)  6 m/s

    B)  4 m/s

    C) 2m/s

    D)  1 m/s

    Correct Answer: A

    Solution :

     \[16=10+3a\] [Here,\[u=10m/s,\upsilon =16m/s,t=3s,\] \[a=2m/{{s}^{2}}\]] and\[10=u+2\times 2\]     [\[u=\]required velocity] \[u=6m/s\] \[(\because t=2s)\]
