A wheel with a radius of R = 1 m rotates around its axis, making one revolution in 0.25 s. Find the speed and acceleration of a point on the wheel rim.
Task data: R (radius of the rotating wheel) = 1 m; T (period of rotation of the taken wheel) = 0.25 s.
1) Speed of a point on the wheel rim: V = 2 * Π * R / T = 2 * 3.14 * 1 / 0.25 = 25.12 m / s.
2) Centripetal acceleration of a point: an = V ^ 2 / R = 25.12 ^ 2/1 = 631 m / s2.
Answer: The point lying on the rim of the wheel has a speed of 25.12 m / s and a centripetal acceleration of 631 m / s2.
