A body is moving with a constant velocity of $4\widehat{\mathrm{i}}+3\widehat{\mathrm{j}}$ , starting from the origin. What will be the position of the body after 10s?

Explanation: The body’s displacement is given by $\mathrm{s}=\mathrm{vt}$. The body starts from the origin hence, the total displacement is the final position of the body. Therefore, after putting in the values, we get, $\mathrm{s}=\left(4\widehat{\mathrm{i}}+3\widehat{\mathrm{j}}\right)*10=40\widehat{\mathrm{i}}+30\widehat{\mathrm{j}}$.
