A force FT is applied to a cord wrapped around a pulley with momentof inertia I = 0.235 kg · m2 and radius R0 = 33.0 cm. (See thefigure.) Suppose the force FT is given by the relation FT = 5.00t -0.10t2 (newtons) where t is in seconds. If the pulley starts fromrest, what is the linear speed of a point on its rim 8.0 s later?Ignore friction.
