A solid sphere (I=(2/5)MR^2) with a radius R=0.10m is attatched to a massless rope by a frictionless axle that passes through the center of the sphere. The rope passes over an ideal pulley and is connected to a 1kg block. The sphere has a mass of 2kg. The surface has a meu that cannot equal 0. Assume that the ball always rolls without slipping and that the system is released from rest. Calculate: a. the acceleration of the system b. the tension in the rope c. the speed of the 1kg mass, by energy methods, after it has descended 0.25m. PLEASE HELP. I HAVE NO IDEA WHAT TO DO!
