Skidding Of Vehicle On A Level Road - Practice Questions & MCQ

A vehicle of mass 5000 Kg starts taking a circular turn of radius 10 m. The initial speed of the vehicle on a circular track is 5 $\mathrm{m} / \mathrm{s}$ and it is increasing with the rate of $1 \mathrm{~m} / \mathrm{s}^2$. After how much time the vehicle will be just about to overturn [Assume distance between two vehicle $=4 \mathrm{~m}$, the height of the center of mass of vehicle $=2 \mathrm{~m}, \mathrm{~g}=10 \mathrm{~m} / \mathrm{s}^2$ ]

The maximum speed of a car on a road turn having a radius of curvature 20m, if the coefficient of friction between the tyres and the road is 0.5  will be - (Take $g=10 \mathrm{~m} / \mathrm{s}^2$)
