A 60 kg body is pushed with just enough force to start it moving across a floor and the same force continues to act afterwards. The coefficient of static friction and sliding friction are 0.5 and 0.4 respectively. The acceleration of the body is

• A.                         \[6\,m/{{s}^{2}}\]               
• B.                         \[4.9\,m/{{s}^{2}}\]            
• C.                         \[3.92\,m/{{s}^{2}}\]                    
• D.                         \[1\,m/{{s}^{2}}\]
