Problem

An object of mass

2\text{ kg}

moves along the horizontal

x

-direction with initial speed

2\text{ m s}^{-1}

. It is displaced through

\vec{x}=(3\hat{i})\text{ m}

by the force

\vec{F}=(2\hat{i}-3\hat{j})\text{ N}

. What is the kinetic energy of the object at the end of the displacement?
