A block of mass 5 kg is on a rough horizontal surface and is at rest. Now a force of 24 N is imparted to it with negligible impulse. If the coefficient of kinetic friction is 0.4 and \[g=9.8\,m/{{s}^{2}}\], then the acceleration of the block is

A.                         \[0.26\,m/{{s}^{2}}\]                      
B.                         \[0.39\,m/{{s}^{2}}\]            
C.                         \[0.69\,m/{{s}^{2}}\]                      
D.                         \[0.88\,m/{{s}^{2}}\]
