Explanation: The linear acceleration of a rotating body can be calculated using the following rule: linear acceleration = (radius)*(angular velocity)^2 We are given that: radius = 0.015 m angular velocity = 5.0 rev/s = 5.0 * 2 * pi = 10 pi rad Substitute with the givens in the above equation to get the linear acceleration as follows: linear acceleration = (0.015) * (10*pi)^2 = 14.8 m/sec^2
