Joe has a 28 foot long board. he needs to cut it into 24 equal length parts. how many feet should each section of the board be?

Using proportions, it is found that each section of the board would have 1.167 feet.

A proportion is a fraction of total amount, and the measures are related using a rule of three.

In this problem, the 24 sections combine to 28 feet. How many feet is there in a single section?

The rule of three is:

24 sections - 28 feet

1 section - x feet

Applying cross multiplication:

Each section of the board would have 1.167 feet.

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
