Answer:
W = 0J
Explanation:
The work done by the dresser is described as
W = f d (cos θ)
F has been given as the weight of this dresser. And it is 3500 N
d = 0 m
When you put these values into the equation
W = 3500 x 0 x cosθ
W = 0 J
This value tells us that the work done on this dresser is zero. No work has been done. Therefore the last option answers the question.

Answer:


Explanation:
<u>Data</u>
<u>mass m= 100g</u>
<u>Length L= 5cm</u>
<u>we can use:</u>
<u>gm-kL= 0</u>
<u>divide both side by m</u>
<u>g - </u> <u>=0</u>
<u>=0</u>
<u>where</u>
 =
 = 
 ^{2}
^{2}
so now
 =
 = 


square both side


We can apply:
u(t)=Acoswt +Bsinwt
u(t)=Acos14t +Bsin14t
u(0)=0  where A=0
 therefore
u(0) = Bsin14t  
 (0) = 10 ⇒ 10=14B ⇒ B=
(0) = 10 ⇒ 10=14B ⇒ B= B=
 B=
so now u(t)= sin14t
sin14t
so t will be:
t=
t=
t=0.22 seconds
 
        
             
        
        
        
Answer:
6.5 seconds.
Explanation:
Given: h=-16t²+679
When the object reaches the ground, h=0.
∴ 0=-16t²+679
collecting like terms,
⇒ 16t²=679
Dividing both side of the equation by the coefficient of t² i.e 16
⇒ 16t²/16 = 679/16
⇒ t² = 42.25
taking the square root of both side of the equation.
⇒ √t² =√42.25
⇒ t = 6.5 seconds.
