A girl weighs 200 newtons. How much work does she do climbing 10 meters of steps?

Sagot :

Assuming that the speed is constant, and the displacement is up (vertical), hence the angle is 0.

Solution:
Work (joules) = 200 N × 10 meters 
                       = 2,000 joules

ANSWER: 2,000 Joules

finding the work:

W = f x d

where W work, F force, D distance.

W= 200 n x 10 m
W= 2,000 nm or 2,000 joules
