Answer is given below:

Explanation:

Given Data:

mass = 80kg

acceleration = 4 ms

force = 800N

Find out:

friction = ?

Formula:

F-friction = weight - f-net

Solution:

weight = (80)(10)

           = 800 N

F-net = ma =(80)(4) = 320N

F-friction = weight - F-net

               =800 N - 320N

               =480N

Answer :

Friction = 480 N

   

The friction force that acts on the firefighter is 480 N is shown below.

Given:

Mass = 80kg

Acceleration = 4 m/s²

Force = 800N

To find:

Friction = ?

What is Friction?

It is a force between two surfaces that are sliding, or trying to slide, across each other.

F-friction = weight - f-net

where,

Weight = (80)(10) = 800 N

F-net = ma =(80)(4) = 320N

F-friction = weight - F-net

F-friction=800 N - 320N

F-friction=480N

Thus, the friction is 480 N is proved.
