A trolley of mass

2\,\text{kg}

is moving on a smooth horizontal track at

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

. A horizontal net force of

4\,\text{N}

acts in the direction of motion for

3\,\text{s}

. (i) Find the change in momentum produced during this time. (ii) Determine the final velocity of the trolley.
