Splet18. jun. 2015 · That tells us that the circumference of the circle that the hand travels in is 63 cm. Since C = 2πr, we can use that to figure out the radius of the circle: r = C / 2π = 63/2π = 10.03 cm. The centripetal acceleration of the hand is v 2 / r, which in this case is (1.05 cm/sec) 2 / 10.03 cm = 0.11 cm / sec 2 SpletThe minute hand of a clock is 7.70 cm long. a) Find the magnitude of the acceleration of its tip.
