    An object accelerates from rest to a velocity 27.5 m/s in 10 sec then find distance covered by object in next 10 sec                                     [BCECE 2004]            

    A)              550 m            

    B)                                  137.5 m            

    C)                         412.5 m          

    D)                                  275 m

    Correct Answer: C

    Solution :

                    u = 0, \[v=27.5\ m/s\] and t = 10 sec             \[\therefore a=\frac{27.5-0}{10}=2.75\ m/{{s}^{2}}\]             Now, the distance traveled in next 10 sec,             \[S=ut+\frac{1}{2}a{{t}^{2}}\]\[=27.5\times 10+\frac{1}{2}\times 2.75\times 100\]             = 275 + 137.5 = 412.5 m
