Physics - Circular Motion Question with Solution | TestHub

A boy runs on a circular path of radius R = 28 m with a constant speed $u=4\mathrm{m}/\mathrm{s}$. Another boy starts from the centre of the path to catch the first boy. The second boy always remains on the radius connecting the centre of the circle and the first boy and maintains magnitude of his velocity constant $\mathrm{V}=4\mathrm{m}/\mathrm{s}$. If the time of chase is $(10+\mathrm{x})\sec$ then $\mathrm{x}=\dots ..;\left(\pi =\frac{22}{7}\right)$
