Answer:
The work done on the wall by the man is 0 J.
To calculate the amount of work done by the man, we use the formula below.
Formula:
W = (ma)d............. Equation 1
Where:
W = Work done on the wall by the man
m = mass of the wall
a = acceleration of the wall
d = distance.
from the question,
Given:
m = 500000 kg
a = 0 m/s² (not moving)
d = 0 m.
Substitute these values into equation 1
W = 500000(0)(0)
W = 0 J.
Hence, the work done on the wall by the man is 0 J.
