146191 Consider a frictionless ramp on which a smooth object is made to slide down from an initial height ' \(h\) '. The distance ' \(d\) ' necessary to stop the object on a flat track (of coefficient of friction ' \(\mu\) '), kept at the ramp end is

146192 A wooden box lying at rest on an inclined surface of a wet wood is held at static equilibrium by a constant force \(\overrightarrow{\mathrm{F}}\) applied perpendicular to the incline. If the mass of the box is \(1 \mathrm{~kg}\) the angle of inclination is \(30^{\circ}\) and the coefficient of static friction between the box and the inclined plane is 0.2 , the minimum magnitude of \(\vec{F}\) is (Use \(g=10 \mathrm{~m} / \mathrm{s}^{2}\) )

146193 A bullet of mass \(4.2 \times 10^{-2} \mathrm{~kg}\), moving at a speed of \(300 \mathrm{~ms}^{-1}\), gets stuck into a block with a mass 9 times that of the bullet. If the block is free to move without any kind of friction, the heat generated in the process will be
