Answer: The work done to lift the 2 N rock was 6 Joules.
Explanation:
Weight of the Rock = 2 Newtons
So, the force required to lift this rock will be equal to its weight or greater than its weight
Minimum force required to lift the Rock = 2 N
Displacement of the Rock when force was applied = 3 m,
Work Done: It is defined as product of force applied to the object into displacement of the object.
[tex]\text{Work done}=Force\times Displacement=2 N\times 3 m=6 Nm=6 Joules[/tex]
The work done to lift the 2 N rock was 6 Joules.
