A block of mass 5kg is lying on a rough horizontal surface. The coefficient of static and kinetic friction are 0.3 and 0.1 and g= 10 ms^(-2) The frictional force on the block is

A block of mass 2 kg is on a horizontal surface. The coefficient of static & kinetic frictions are 0.6 & 0.2 The minimum horizontal force required to start the motion is applied and if it is continued, the velocity acquired by the body at the end of the 2nd second is (g= 10ms^2 )

A horizontal force just sufficient to move body of mass 4 kg lying on a rough horizontal surface, is applied on it. Coeficients of static and kinetic frictions are 0.8 and 0.6 respectively. If the force continues to act even after the body has started moving, the acceleration of the body is (g=10 ms^-2)
