The figure below shows, at left, a solid flywheel of radius R = 0.600 m and mass 50.0 kg.RMounted directly to it and coaxial with it is a pulley with a much smaller mass and a radius of r = 0.230 m. The flywheel and pulley assembly are on a frictionlessaxle. A belt is wrapped around the pulley and connected to an electric motor as shown on the right. The turning motor gives the flywheel and pulley a clockwiseangularration of 1.67 rad/s2. The tension T, in the upper (taut) segmentthe belt is 175 N.(a) What is the tension (in N) in the lower (slack) segment of the belt?(b) What If? You replace the belt with a different one (one slightly longer and looser, but still tight enough that it does not sag). You again turn on the motor sothat the flywheel accelerates clockwise. The upper segment of the belt once again has a tension of 175 N, but now the tension in the lower belt is exactlyzero. What is the magnitude of the angular acceleration (in rad/s?)?rad/s2

The figure shows an elaborate pulley consisting of four small spheres and a uniform disk, all of which rotate together. Each sphere has a mass m = 4.46 kg, is held a distance of 0.29 m from the pulley's center by a massless spoke, and is small enough that it can be considered a point mass. When a block of mass M =10.5 kg is attached as shown and released from rest, the ideal rope turns the pulley without slipping as the block descends. Calculate the block's speed v after falling a distance of 0.73 m, if the pulley's mass and radius are mp = 3.26 kg and R = 0.1 m. m mp V= M m/s Record your numerical answer below, assuming three significant figures.
