Given the position-versus-time graph (in black) of an object in motion and the tangent line to the graph at the time point of \(10\) seconds (in red), find the instantaneous velocity of this object at \(10\) seconds. (Hint: Instantaneous velocity can be expressed as the derivative of position function with respect to time: \(v(t)=\frac{\mathrm{d}s}{\mathrm{d}t}\).)
\( 2 \,\frac{\mathrm{m}}{\mathrm{s}}\)
\( 0.5 \,\frac{\mathrm{m}}{\mathrm{s}}\)
\( 1 \,\frac{\mathrm{m}}{\mathrm{s}}\)
\( 30\,\frac{\mathrm{m}}{\mathrm{s}}\)
