Problem: A cord is wrapped around a wheel which is initially at rest as shown. If a force is applied to the cord and gives it an acceleration a = (4t) m/s² , where t is in seconds determine as a function of time (a) the angular velocity of the wheel, (b) the angular position (0) of the line OP in radians. Express all answer in terms of t, that is in question (a) express w in terms of t and in (b) express e in terms of t. Hint: Solve first for a from a, ... r = 0.2 m- P az = ar F
