A block of mass \[M=5\,kg\] is resting on a rough horizontal surface for which the coefficient of friction is 0.2. When a force \[F=40\,\,N\] is applied, the acceleration of the block will be \[(g=10\,\,m/{{s}^{2}})\] [MP PMT 2004]

• A.             \[5.73\,\,m/{{\sec }^{2}}\]   
• B.             \[8.0\,\,m/{{\sec }^{2}}\]
• C.  \[3.17\,\,m/{{\sec }^{2}}\]
• D.             \[10.0\,\,m/{{\sec }^{2}}\]
