If your weight is 132 pounds, how much work is done if you climb a flight of stairs 12 meters high?

7040.76 Joule

Step-by-step explanation:

In order to make yourself be able to climb upstairs, you need to work against the force of gravity. The force with which you pull yourself up is equal to the force of gravity exerted on you by the gravitational force.

So here, the net force involved is Mass(in Kg) multiplied by Acceleration due to gravity.

132 pounds = 59.8742 Kg

Net force = 59.87 × 9.8 = 586.73

As we know, the workdone is calculated by Multiplying the Net force with the Net displacement. Here, in this case the net displacement is 12 meters.

So,

Workdone = 586.73 × 12 = 7040.76 Joule

the answer is c

hope this !
