Problem

A trolley of mass

1000\,\text{kg}

starts from rest and accelerates uniformly at

0.5\,\text{m/s}^{2}

over a straight track

40\,\text{m}

long. How much work is done on the trolley during this motion? a)

4.0\times10^{4}\,\text{J}

2.0\times10^{4}\,\text{J}

1.0\times10^{4}\,\text{J}

8.0\times10^{4}\,\text{J}
