\;\;\underline{\textbf{\textsf{ Given:-}}}

• Initial velocity, u= 60.0 m/s

• Acceleration, a = 5.0 m/s²

• Displacement, s = 600 m

\;\;\underline{\textbf{\textsf{ To Find :-}}}

• Final velocity, v

\;\;\underline{\textbf{\textsf{ Solution :-}}}

\underline{\:\textsf{We know that   :}}

\boxed{\sf v^{2} - u^{2} = 2as}

(\bf 3rd \:  equation  \: of  \: motion)

\underline{\:\textsf{Now,  put the given values   :}}

 \rm \dashrightarrow  {v}^{2}  =  {60}^{2}  + 2 \times 5 \times 600 \\  \\  \rm\dashrightarrow   {v}^{2}  = 3600 + 6000 \\  \\  \rm\dashrightarrow  {v}^{2}  = 9600 \\  \\  \rm  \dashrightarrow v =  \sqrt{9600}  \\  \\  \rm \dashrightarrow v = 97.98 \: m {s}^{ - 1}

\;\;\underline{\textbf{\textsf{ Hence-}}}

\underline{\textsf{Final velocity   is \textbf{97.98m/s}}}.

\;\;\underline{\textbf{\textsf{ Know  More:-}}}

(\bf 1st\:  equation  \: of  \: motion)

1.\boxed{\sf v = u + at}

(\bf 2nd \:  equation  \: of  \: motion)

2.\boxed{\sf s = ut + \frac{1}{2} at^{2}}

(\bf 3rd \:  equation  \: of  \: motion)

3.\boxed{\sf v^{2} - u^{2} = 2as}

Where,

›› s = Distance Covered

›› u = Initial Velocity

›› t = Time taken

›› v = Final Velocity

›› a = Acceleration
