1.	A small block slides along a path which is smooth until the block reaches the section of length L = 3m, which begins at height h = 3m on a flat incline of angle 37∘, as shown in the figure. In that section, the coefficient of kinetic friction is 0.50. The block passes through point A with a speed of √136 m/s. Find the speed (in m/s) of the block as it passes through point B where the friction ends. (g=10m/s2) ___
Answer» A small block slides along a path which is smooth until the block reaches the section of length L = 3m, which begins at height h = 3m on a flat incline of angle $37^{\circ}$ , as shown in the figure. In that section, the coefficient of kinetic friction is 0.50. The block passes through point A with a speed of $\sqrt{136}$ m/s. Find the speed (in m/s) of the block as it passes through point B where the friction ends. ( $g = 10 m / s^{2}$ ) ___

A horizontal curve with superelevation e = 0.05 (note, e=tanβ ) has a posted speed limit of 60 km/h. For this speed limit, only those vehicles with Y/X ratio(in figure) greater than 2 and travelling at speeds greater than 1.2 times the speed limit, will overturn. However, with recent increase in truck traffic the speed limit needs to be modified such that only those vehicles with Y/X ratio greater than 3 and travelling at more than 1.2 times the speed limit will overturn. What should be the new speed limit?(in km/hr round off to integer) (with respect to the figure, assume that the vehicle is travelling into the plane of the paper).50
