<u>Answer</u>
<em>The total displacement of the object is 320 m</em>
<u>Solution-</u>
From the formulas of mechanics,

Where,
s = displacement 
u = initial velocity = 0               ( ∵ As the body was in rest in the beginning )
t = time taken = 8 s
a = acceleration = -10 m/s²      ( ∵ -ve is because of the downward motion)
Putting all the values,
 ( ∵ -ve displacement means it is in downwards)
 ( ∵ -ve displacement means it is in downwards)

Answer:
μv =
σv= 
Step-by-step explanation:
Volume is found by multiplying the area and height. Since we're given both area and height of 10 and 5 cm respectively then
μv =A.h= 10*5= 50 cm^{3}
The standard deviation of the volume will be
σv= 0.3*10=
