Problem

An object of mass

2 \text{ kg}

moving along horizontal

x

-direction with initial speed

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

is displaced through

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

by the force

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

. The kinetic energy of the object at the end of the displacement

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