Answer:

149.96J

Step-by-step explanation:

Given parameters:

Number of stairs = 33

Height = 0.25m

Weight = 599.85N

Unknown:

Energy the person takes to reach the top = ?

Solution:

To solve this problem;

The energy it takes is given as:

Energy = weight x height

Energy = mass x gravity x height

Now,

Insert the given parameters and solve;

Energy = 599.85 x 0.25 = 149.96J
