Question

Determine the work performed by a person with a weight of 750N, while climbing 20 stairs, if it is known that the height of each step is 20 cm.

Answer 1

3000J

Step-by-step explanation:

- formula work done is force x perpendicular distance.

- convert 20cm to m, so 20 divide by 100 equals 0.2.

- since there is 20 stairs, 20 multiply by 0.2m.

- lastly, 750N x 4m equals 3000J
