[" Q8: A particle moves along a semicircle "],[" of radius "10m" in "5" seconds.The "],[" average velocity of the particle is "]

In 1 s, a particle goes from point A to point B, moving along a semicircle of radius 1 m. The magnitude of the average velocity of the particle is

.A particle moves along a circle of radius (20)/(pi) m with constant tangential acceleration.If the velocity of the particle is "80m/s" at the end of the second revolution after motion has begun,the tangential acceleration is :-
