W = ∫ (x from 0.1 to +oo) F dx 
= ∫ (x from 0.1 to +oo) A e^(-kx) dx 
= A/k x [ - e^(-kx) ](between 0.1 and +oo) 
= A/k x [ 0 + e^(-k * 0.1) ]

= A/k x e^(-k/10) </span>
        
             
        
        
        
Answer:
T = 4.905[N]
Explanation:
In order to solve this problem we must perform a sum of forces on the vertical axis.
∑Fy = 0
We have two forces acting only, the weight of the body down and the tension force T up, as the body does not move we can say that it is system is in static equilibrium, therefore the sum of forces is equal to zero.
![T-m*g=0\\T=0.5*9.81\\T=4.905[N]](https://tex.z-dn.net/?f=T-m%2Ag%3D0%5C%5CT%3D0.5%2A9.81%5C%5CT%3D4.905%5BN%5D)
 
        
             
        
        
        
Area is 2-dimensional which means it has a length and a width area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle multiply the length by the width.
