\large\underline{\sf{\red{Given:-}}}

\dag\: \sf{Rate :- 0.2m/s^2}

\dag\: \sf{Time :- 1 min }

\dag\: \sf{Initial\: Velocity :- 0m/s}

\large\underline{\sf{\red{To Find:}}}

\sf{Velocity \:attained\: by\: it\: in\: 1\: minute}

\large\underline{\sf{\red{Solution :}}}

Concept :

\dashrightarrow\: \sf{Velocity:- Velocity\: is \:the\: rate\: of\: change\: of\: the}

\sf{position\: of \:an\: object}

\dashrightarrow\: \sf{Formula :- \large\ \frac{Displacement}{Time} }

\dashrightarrow\: \sf{It\: is \:a \:vector\: quantity.}

\dashrightarrow\: \sf{Its \:S.I. \:unit\: is \:m/s.}

\sf{First \:equation \:of\: kinematics :}

\underline{\boxed{\sf{v=u+at}}}

Where,

⇛ v denotes final velocity

⇛ u denotes initial velocity

⇛ a denotes acceleration

⇛ t denotes time

Conversion:

\implies\: \sf{1\: minute = 60 sec}

Calculation:

\implies\: \sf{v=u+at}

\implies\: \sf{v=0+0.2\times 60}

\implies\: \underline{\boxed{\sf{v=12m/s}}}

\sf{Hence\:the\: velocity\:will\:be\:12m/s}
