An object at rest at the origin begins to move in the +x+x direction with a uniform acceleration of 1 m/s21 \mathrm{~m} / \mathrm{s}^{2} for 4 s4 \mathrm{~s} and then it continues moving with a uniform velocity of 4 m/s4 \mathrm{~m} / \mathrm{s} in the same direction. The x−t\mathrm{x}-\mathrm{t} graph for object's motion will beAn object at rest at the origin begins to move in the +x direction with a uniform acceleration of 1 ~m / s^ 2 for 4 ~sAn object at rest at the origin begins to move in the +x direction with a uniform acceleration of 1 ~m / s^ 2 for 4 ~sAn object at rest at the origin begins to move in the +x direction with a uniform acceleration of 1 ~m / s^ 2 for 4 ~sAn object at rest at the origin begins to move in the +x direction with a uniform acceleration of 1 ~m / s^ 2 for 4 ~s

Step-by-step solution

V=0+1×tdxdt=tdx=tdtx∝t2………Parabolicdxdt=4dx=4dtx∝t………Linear\begin{array}{l}\mathrm{V}=0+1 \times \mathrm{t}\\ \frac{d x}{d t}= t \\ d x=t \mathrm{dt}\\ x \propto t^{2} \quad \ldots \ldots \ldots \\ Parabolic \frac{d x}{d t}=4 \\ d x=4 d t \\ x \propto t \quad \ldots \ldots \ldots Linear \end{array}
