    The velocity of a particle at an instant is 10 m/s. After 3s 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) 2 m/s                    

    D)        1 m/s

    Correct Answer: A

    Solution :

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