Problem

A toy car of mass

0.20\,\text{kg}

is initially moving at

2.0\,\text{m}\,\text{s}^{-1}

along a straight track. A constant horizontal force of

1.2\,\text{N}

acts in the direction of motion over a distance of

1.5\,\text{m}

. Determine the translational kinetic energy of the car after it has moved the

1.5\,\text{m}

under the influence of the force.
