(a) An object moves from an initial position at \(x_{\mathrm{i}}=+3.1 \mathrm{~m}\) to a final position at \(x_{f}=+1.4 \mathrm{~m}\). What is the \(x\) component of the object's displacement?

(b) The \(x\) component of an object's displacement is \(+2.3 \mathrm{~m}\). If the object's initial position is at \(x_{\mathrm{i}}=+1.6 \mathrm{~m}\), what is the \(x\) coordinate of its final position?

(c) After undergoing a displacement of \(-1.3 \mathrm{~m}\), an object is at \(x_{\mathrm{f}}=-0.4 \mathrm{~m}\). What is the \(x\) coordinate of the object's initial position?
