Problem

A crane lifts a

2.0\times10^{3}\,\text{kg}

container vertically upward through

8.0\,\text{m}

. Take

g = 9.8\,\text{m/s}^2

. Ignoring air resistance, calculate the total work done on the container by the crane. (a)

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

(b)

1.6\times10^{6}\,\text{J}

(c)

1.6\times10^{5}\,\text{J}

(d)

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