372137 If coefficient of static friction is \(\mu_{\mathrm{s}}\) and coefficient of kinetic friction is \(\mu_{\mathrm{k}}\), which is correct?

372138 The coefficient of friction between the tyres and the road is 0.25 . The maximum speed with which car can be driven round a curve of radius \(40 \mathrm{~m}\) without skidding is (assume \(\mathrm{g}=10\) \(\mathbf{m s}^{-2}\) )

372139 A block rests on a rough horizontal surface, \(\mu\) is the coefficient of friction between the block and the surface. A force mg pulls the block. This force acts an angle \(\theta\) with the vertical side of the block. The mass of the block is \(\mathrm{m}\). The block can be pulled along the surface, if \(\cot \frac{\theta}{2}\)

372140 An army vehicle of mass \(1000 \mathrm{~kg}\) is moving with velocity of \(10 \mathrm{~m} / \mathrm{s}\) and is acted upon by a forward force of \(1000 \mathrm{~N}\) due to the engine and a retarding force of \(500 \mathrm{~N}\) due to the friction. What will be its velocity after \(10 \mathrm{~s}\) ?
