A 300 N rock is lifted 2 meters high in 5 seconds. How much work is done on the rock?
To calculate the work done on the rock, we can use the formula:
Work = Force * Distance
Given that the force acting on the rock is 300 N and the distance it is lifted is 2 meters, we can substitute these values into the formula:
Work = 300 N * 2 m
Now, we multiply the force and distance:
Work = 600 N·m
The unit for work is joules (J), so the final answer is 600 J. Therefore, 600 J of work is done on the rock.
