In case of circular motion,Ï$$2$$âÏ$$02=2$$Î±Î¸ âµ$$v2$$â$$u2=2as$$Ï$$2=2$$Î±Î¸ âµÏ$$0=0or$$      $$vr2=2ar$$Î¸ $$($$âµ$$a=r$$Î±$$)or$$      $$a=V22r$$Î¸Given that r $$=$$ (20/$$Ï$$) metre, V $$=$$ $$80$$ $$m/s$$ and Î¸ $$=$$ $$4$$Ï radian.Substituting these values, we $$geta=40m/s2$$

A particle moves along a circle of radius $(\frac{20}{Ï}) m$ with constant tangential acceleration. It the velocity of the particle is 80 m/s at the end of the second revolution after motion has begun, the tangential acceleration is
