How much work is done by the force of gravity when a 45 N object falls to the ground from a height of 4.6 m?
2 answers:
Work Done = 45N x 4.6m = 207J
Answer:
207Nm
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.

I really doubt because the universe is supposed to be infinite
Distance = (speed) x (time)
Distance = (0.5 m/s) x (2.3 s)
Distance = (0.5 x 2.3) m
Distance = 1.15 meters
