146183 If the coefficient of static friction between shoes of a runner and the track is 0.85 , the greatest acceleration that can be generated by the runner is (here, \(g\) gravitational acceleration)

146184 A body of mass \(m=1 \mathrm{~kg}\) is moving in a medium and experiences a fractions force \(F=-k v\), where \(v\) is the speed of the body. The initial speed is \(v_{0}=10 \mathrm{~ms}^{-1}\) and after \(10 \mathrm{~s}\), its energy becomes half of initial energy. Then, the value of \(k\) is

146185 Two charged particles of each of mass \(3 \mathrm{~g}\) and charge \(0.2 \mu \mathrm{C}\) stay in (vacuum) equilibrium on a horizontal surface with a separation of \(20 \mathrm{~cm}\). the coefficient of friction is

146186 Two wedges each of mass \(600 \mathrm{~g}\) are placed next to each other on a rough horizontal surface. The coefficient of static friction between the wedges and the surface is 0.4 . A cube of mass ' \(M\) ' is balanced on the wedges as shown in the figure. If there is no friction between the cube and wedges, the largest mass ' \(M\) ' of the cube that can be balanced without motion of the wedges is \(\mathbf{k g}\).
