Consider the following statements 
(A) If speed $\left(\mathrm{i}.\mathrm{e}.,\left|\frac{\mathrm{dx}}{\mathrm{dt}}\right|\right)$ is decreasing, then velocity $\left(\mathrm{i}.\mathrm{e}.,\mathrm{v} =\frac{\mathrm{dx}}{\mathrm{dt}}\right)$ and acceleration $\left(\mathrm{i}.\mathrm{e}.,\mathrm{a}=\frac{\mathrm{d\nu }}{\mathrm{dt}}\right)$ must have opposite sign.
(B) If modulus of a variable is decreasing, the variable and its derivative must have opposite sign.
