A CD has a mass of 17 g and a radius of 6.0 cm. When inserted into a player, the CD starts from rest and accelerates to an angular velocity of 21 rad/s in 0.80 s. Assuming the CD is a uniform solid disk, determine the net torque acting on it.© BrainMass Inc. brainmass.com March 4, 2021, 5:48 pm ad1c9bdddf
m = 17 *10^(-3) kg
r = 6*10^(-2) m
w = final angular velocity = 21 rad/s
t = 0.8 ...
Newtons Second Law for Rotation is examined. The torque is determined.
