Answer:
207Nm
Step-by-step explanation:
Work on said to be done when an applied force causes an object to move through a particular distance. mathematically,
Work done = Force(f)×distance in the direction of force.
Given force of gravoty = 45N
Height = corresponding Distance= 4.6m
Work done = 45×4.6
Work done= 207Nm
This shows that 207Nm of work is done by the force of gravity when a 45 N object falls to the ground from a height of 4.6 m.
