Answer:

a) 3.5 m

b) 14 secs

c) 1.4 secs

Explanation:

<u>a)  Determine the distance the particle will travel</u>

given velocity ( final velocity ) = 5 m/s

v^2 = u^2 + 2as

s = ( v^2 - u^2 ) / 2a

  = ( 5^2 - 8^2 ) / 2 ( -0.5 * 5^3/2 )

  = 3.5 m

<u>b) Determine the time when v = 1m/s</u>

V = u + at

1 = 8 + (  -0.5 * 1^3/2 ) * t

∴ t = 14 secs

c) Determine the time required for particle to travel 8 m

<em>we will employ both equations above </em>

V^2 = u^2 + 2as

s = 8 m , V = unknown , u = 8 m/s   back to equation

V^2 = 8^2 + 2 ( - 1/2 * V^3/2 ) * 8

∴ V^2 + 8V^3/2 - 64 = 0

resolving the above equation

V = 3.478 m/s

now using the second equation

V = u + at

3.478 = 8 + ( - 1/2 * 3.478^3/2 ) * t

hence : t = 1.4 secs

A loss in value caused by an undesirable or hazardous influence offsite is which type of depreciation?
Lubov Fominskaja [6]

External depreciation may be defined as a loss in value caused by an undesirable or hazardous influence offsite.

<h3>What is depreciation?</h3>

Depreciation may be defined as a situation when the financial value of an acquisition declines over time due to exploitation, fray, and incision, or obsolescence.

External depreciation may also be referred to as "economic obsolescence". It causes a negative influence on the financial value gradually.

Therefore, it is well described above.
