If the stone makes *22* revolutions in *44* seconds, what is the magnitude and direction of acceleration of the stone? Options 1. pi^2 ms-2 and direction along the tangent to the circle. 2. pi^2 ms-2 and direction along the radius towards the centre. 3.pi^2/{4} ms-2 and direction along the radius towards the centre. 4. pi^2 ms-2} and direction along the radius away from the centre. Question: A particle moves along a circle of radius 20ππ20​ m with constant tangential acceleration. If the velocity of the particle is 80 m/s at the end of the second revolution after motion has begun, the tangential acceleration is: Options: 40 msβˆ’2 640Ο€ msβˆ’2 160Ο€ msβˆ’2 40Ο€ msβˆ’2 The engine of a car produces an acceleration of 4 m/sΒ² in the car.
