A particle experiences a variable force $\displaystyle \overrightarrow{\mathrm{F}}=\left(4 x \hat{i}+3 y^2 \hat{j}\right)$ in a horizontal $\displaystyle x-y$ plane. Assume distance in meters and force is newton. If the particle moves from point $\displaystyle (1,2)$ to point $\displaystyle (2,3)$ in the $\displaystyle x-y$ plane, then Kinetic Energy changes by :
