Question

An object rotates about a fixed axis, and the angular position of a reference line on the object is given by θ(t) = 0.4e^(2t), where θ is in radians, and t is in seconds. [a.] What is the object's angular acceleration at t = 2 s? [b.] What is the tangential AND centripetal acceleration of a point on the object that is 4.0 cm from the axis of rotation?
