A wheel (radius = 0.20 m) starts from rest and rotates with a constant angular acceleration of 2.0 rad/s2 . At the instant when the angular velocity is equal to 1.2 rad/s, what is the magnitude of the total linear acceleration of a point on the rim of the wheel?
a. 0.40 m/s2
b. 0.29 m/s2
c. 0.69 m/s2
d. 0.49 m/s2
e. 0.35 m/s2
