The point moves in a circle so that the time dependence of the path is given by the equation s=A-2t t2 (m). Find the linear velocity of the point, its tangential, normal and full acceleration 3 s after the start of movement, if it is known that the normal acceleration of the point at t=2 c is 0.5 m/s2. Find the path traveled by the body in 3 s.
