A spool of thread consists of a cylinder of radius R₁ 4.5 cm with end caps of radius R₂ 9.0 cm as depicted in the end view shown in the figure below. The mass of the spool, including the thread, is m = 280 g. The spool is placed on a rough, horizontal surface so that it rolls without slipping when a force T 0.620 N acting to the right is applied to the free end of the thread. For the moment of inertia treat the spool as being a solid cylinder of radius R₁, as the extended edges are thin and therefore light. (a) What is the acceleration of the spool? Take positive to be to the right. .739 m/s² (b) Determine the direction of the force of friction. to the left to the right Ostraight up O straight down
