How much force does the table exert on the ball to bring it to rest?
  
The acceleration (\(a\)) is,
 
From the Newton's second law, We know that,
 
Acceleration\(=\)  \(m\ s^{-2}\)
 
(Note: Enter your answer with two decimal digits)
 
Force exerted by the table \(=\)  \(N\)
 
(Note: Enter your answer with four decimal digits)
