Answer» nfo : A wheel of 30cm in radius rotate at the rate of 180 revolution per minute.To find : The centripetal acceleration of a POINT on the EDGE of wheel is ...solution : radius of wheel, r = 30 cm = 0.3 m ANGULAR velocity of wheel, ω = 180 rev/min = 180 × 2π/60 rad/s = 6π rad/s now centripetal acceleration, a = rω² = 0.3 × 6π m/s² = 1.8 × 3.14 m/s² = 5.652 m/s² Therefore the centripetal acceleration of a point on the edge of wheel is 5.652 m/s². |
