Answer: 1200 joules
Explanation:
Work is done when force is applied on an object over a distance. It is measured in joules.
Thus, Work = Force X Distance
Since Force = 300 newton
Total distance = (distance off the ground + distance travelled on the ground)
i.e 2 meters off + 2 more meters = 4metres
Work = Force X Distance
= 300 Newton X 4 metres
= 1200 joules
Thus, Rocky did 1200 joules of work on the
rock
