A spherical ball of radius 3×10−4m and density 104kg/m3 falls freel

1.	A spherical ball of radius 3×10−4m and density 104kg/m3 falls freely under the gravity through a distance h before entering a tank of water. If after entering the water the velocity of the ball doesn’t change, find h. [Viscosity of water=9.8×10−6N−s/m2 and g=9.8m/s2]
Answer» A spherical ball of radius $3 \times 10^{- 4} m$ and density $10^{4} k g / m^{3}$ falls freely under the gravity through a distance h before entering a tank of water. If after entering the water the velocity of the ball doesn’t change, find h. $[V i s c o s i t y o f w a t e r = 9.8 \times 10^{- 6} N - s / m^{2} a n d g = 9.8 m / s^{2}]$

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
