A block of mass 2.5 Kg is kept on a rough horizontal surface. It is found that the block does not slide if a horizontal force less than 15 N is applied to it. Also it is found that it takes 5 seconds to slide through the first 10 m if a horizontal force of 15 N is applied and the block is gently pushed to start the motion. Taking `g=10 m/s^2`, calculate the coefficient of static and kinetic friction between the block and the surface.

A

`mu_(s) = 0.60`

B

`mu_(c ) =0.52`

C

`mu_(k) = 0.60`

D

`mu_(s)= 0.52`
