Answer:

Option B

More work is done raising the car

Explanation:

Given;

  • “Man lifting 800 N weights 2 meters”
  • Applied Force = 800 Newton
  • Total Displacement = 2 meter
  • “2000 N car being raised 1 meter”
  • Applied Force = 2000 Newton
  • Total Displacement = 1 meter

To Find;

  • Work done = ?

For picture 1

W = F • d

W = 800 • 2

W = 1600 Nm

For picture 2

W = F • d

W = 2000 • 1

W = 2000 Nm

Thus, For picture 1, Work done is 1600 Nm and For picture 2, work done is 2000 Nm

So, More work is done raising the car.
