Question

If you do 1500 J of work running up stairs and your weight in Newtons is 900 N, how

high are the stairs?

Answer 1

The stairs are at the height of 1.67 m.

Step-by-step explanation:

Given data:

work done = 1500 J

Force = 900 N

Height of stairs = ?

Solution:

Work = force × distance

w = f × d

d = w/ f

d = 1500 kg. m².s⁻² /900 Kg.m/ s²

d = 1.67 m

The stairs are at the height of 1.67 m.
