A body starts with some initial velocity and a constant acceleration. It covers a distance of 200 m in first four second and a distance of 220 m in next two second. The acceleration of the body and its velocity at the end of seventh second are

\[a=150\,m{{s}^{-2}},\,\upsilon =10\,m{{s}^{-1}}\]

\[a=5\,m{{s}^{-2}},\,\,\upsilon =75\,m{{s}^{-1}}\]

\[a=7.5\,m{{s}^{-2}},\,\upsilon =100\,m{{s}^{-1}}\]

\[a=20\,m{{s}^{-2}},\,\upsilon =150\,m{{s}^{-1}}\]
