Yes it does, uh huh.  It slows down as it rolls.  That's a fact.
In order for the ball to roll forward, it has to push grass out of the way.  That takes energy.  To bend each blade of grass out of its way, the ball has to use a tiny bit of the kinetic energy that it has, so it gradually runs out of kinetic energy.  When its kinetic energy is all gone, it stops moving. 
 
        
             
        
        
        
With its apparent magnitude 
        
                    
             
        
        
        
Answer:
The tension is  
Explanation:
The free body diagram of the question is shown on the first uploaded image From the question we are told that 
            The distance between the two poles is 
           The mass tied between the two cloth line is  
          The distance it sags is 
The objective of this solution is to obtain the magnitude of the tension on the ends of the  clothesline 
Now the sum of the forces on the y-axis is zero assuming  that the whole system is at equilibrium 
        And this can be mathematically represented as
                              
  To obtain  we apply SOHCAHTOH Rule
 we apply SOHCAHTOH Rule 
  So    
           ![\theta = tan^{-1} [\frac{opp}{adj} ]](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20tan%5E%7B-1%7D%20%5B%5Cfrac%7Bopp%7D%7Badj%7D%20%5D)
             ![= tan^{-1} [\frac{1}{7}]](https://tex.z-dn.net/?f=%3D%20tan%5E%7B-1%7D%20%5B%5Cfrac%7B1%7D%7B7%7D%5D)
