Twoinclined frictionless tracks, one gradual and the other steep meet

1.	Twoinclined frictionless tracks, one gradual and the other steep meet atA from where two stones are allowed to slide down from rest, one oneach track (Fig. 6.16). Will the stones reach the bottom at the sametime? Will they reach there with the same speed? Explain. Given θ1= 30°,θ2= 60°,and h =10 m, what are the speeds and times taken by the two stones?

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
