Question 9 (Mandatory) (1 point)

Falls often cause injuries, so one of the significant aspects of falls is the displacement and motion of a body. It is defined as how far a body moves vertically during the fall. Accordingly, there are three important factors that should be known to compute the kinetic energy (KE) of a falling body. These factors are:

Question 9 options:

	1) The velocity of the falling body (v), the distance of the falling body (s), and the weight of the falling body (w)
	2) The acceleration of gravity for the falling body (G), the velocity of the falling object (v), and the distance of the falling body (s)
	3) The velocity of the falling body (v), the contact area (A), and the acceleration of gravity (G)
	4) The impact limits of the falling body, the velocity of the falling body (v), the distance of the falling object (s)

Answer 1

8) 4-good housekeeping ( It includes checking spills and wet regions and cleaning spills, wiping or clearing garbage from floors ,expelling obstructions from walkways and continually keeping them free of messiness securing (attaching, taping, and so forth.)

9) 1-The velocity of the falling body (v), the distance of the falling body (s), and the weight of the falling body (w)

(velocity mass can be used to determine the kinetic energy of the falling body and mass ,velocity, distance can be used to determine the potential energy. with the help of KE and PE we can determine the impact force)

10) 3-5000 lbs ( A harbor for an individual fall capture framework might be fit for supporting 5000 lbs of dead weight for every laborer fixing off to it.)

11) 2- observation ( It is fundamental step to be carried out before proceding any activity or task)

12) 1-True (Ear muffs consists of sound attenuating material and soft ear cushions thet fit around the ear and provide protection against high frequency noise.)
