A flywheel with radius 0.300m starts from rest and accelerates with a constant angular acceleration of 0.600rad/s^2.?
For a point on the rim of the flywheel, what are the magnitudes of the tangential, radial and resultant accelerations after 2.00s of acceleration?

angular acceleration α = 0.600 rad/sec
tangential acceleration at = α*r = 0.60*0.3 = 0.18 m/sec^2
angular speed ω = α*t = 0.6*2 = 1.2 rad/sec
radial acceleration ar = ω^2*r = 1.2^2*0.3 = 0.432 m/sec^2
resultant acceleration a = √at^2+ar^2 = √0.18^2+0.432^2 = 0.468 m/sec^2
