1.	Two small balls of masses ′m′ and ′2m′ are placed in a fixed smooth horizontal circular hollow tube of mean radius ′r′ as shown. The ball of mass ′m′ is moving with speed ′u′ and the ball of mass ′2m′ is stationary. After their first collision, the time elapsed for next collision is: (coefficient of restitution e = 12)
Answer» Two small balls of masses $^{'} m^{'}$ and $^{'} 2 m^{'}$ are placed in a fixed smooth horizontal circular hollow tube of mean radius $^{'} r^{'}$ as shown. The ball of mass $^{'} m^{'}$ is moving with speed $^{'} u^{'}$ and the ball of mass $^{'} 2 m^{'}$ is stationary. After their first collision, the time elapsed for next collision is: (coefficient of restitution $e$ = $\frac{1}{2}$ )

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
