1. A wheel 30 cm in radius rotate at a rate of 180 rpm. Determine the centripetal acceleration of a point on the edge of wheel. Given: Radius (r) = 30 cm = 0.3 m Angular speed (0) = 180 revolutions / 60 seconds = (6.28 radians) / second = Find: centripetal acceleration (ac) of r = 0.3 m Solution: The magnitude of the centripetal acceleration: ac =r o 2 revolutions/ second = (3) %3D radians/second ac = de =
