A$($n$)0\mathrm{.}5$ kg object is at rest at the origin of acoordinate system. A$($n$)3\mathrm{.}18$ N force in the$+$x direction acts on the object for $1\mathrm{.}58.$ At the end of this interval, a constant forceof $6\mathrm{.}08$ N is applied in thex direction for$4\mathrm{.}33$ s$.$What is the velocity at the end of the $4\mathrm{.}33$ s$?$Answer in units of m$/$s$.$
