A force FT is applied to a cord wrapped around a pulley with moment of inertia I = 0.295 kg · m2 and radius R0 = 33.0 cm. (See the figure.) Suppose the force FT is given by the relation FT = 4.00t ? 0.10t2 (newtons) where t is in seconds. If the pulley starts from rest, what is the linear speed of a point on its rim 7.0 s later? Ignore friction.
