Answer:

0J

Explanation:

No work is being done on the wall by the man pushing on it.

 Given parameters:

Mass of man  = 75kg

Mass of wall  = 500000kg

Time  = 250s

Unknown:

Work done  = ?

Solution:

Work done is the force applied on a body that moves it along a particular path.

For work to be done, distance must be move or displacement must occur.

Since the wall is not moving the distance is 0;

    Work done  = Force x distance

Since distance is 0m, work done is 0J

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.
