Asked by Mary

A flywheel of a radius .5 m starts from rest and under goes a uniform angular acceleration of 3 rad/sec2 for a period of 5 seconds. Find the angular velocity of the flywheel at the end of this time? Find the angular displacement (in radians) that the wheel turns through during this time?

ω=ε•t =3•5 = 15 rad/s
φ = ε•t²/2 = 3•25/2 = 37.5 rad
