146173 A car moves at a speed of \(36 \mathrm{~km} / \mathrm{h}\) on a level road. The coefficient of friction between the car tyres and the road is 0.8 . The car negotiates a curve of radius \(R\). if \(g=10 \mathrm{~ms}^{-2}\) the car will skid (or slip) while negotiating the curve, if the value of \(R\) is

146174 A cyclist comes to a skidding stop in \(10 \mathrm{~m}\). During this process, the force on the cycle due to the road is \(200 \mathrm{~N}\) and is directly opposed to the motion. How much work does the road do on the cycle?

146175 A block rests on a rough inclined plane making an angle of \(30^{\circ}\) with the horizontal. The coefficient of static friction between the block and the plane is 0.8 . If the frictional force on the block is \(10 \mathrm{~N}\), the mass of the block is (Take \(\mathbf{g}=10 \mathbf{m s}^{-2}\) )

146176 A boy of mass \(50 \mathrm{~kg}\) is climbing a vertical pole at a constant speed. If coefficient of friction between his palms and the pole is 0.75 . The normal reaction between him and the pole is (take, \(g=10 \mathrm{~m} / \mathrm{s}^{2}\) )
