A point moves with deceleration along the circle of radius R so that at any moment of time its tangential and normal accelerations are equal in moduli. At the initial moment t = 0 the velocity of the point equals v0. Find: (a) the velocity of the point as a function of time and as a function of the distance covered s; (b) the total acceleration of the point as a function of velocity and the distance covered. |
