A block of mass 5kg 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=9.8m//s^(2)` , then the acceleration of the block is
A. `0.26m//s^(2)`
B. `0.39m//s^(2)`
C. `0.69m//s^(2)`
D. `0.88m//s^(2)`
