IVI m1 m2 Two blocks with masses m1 =7 kg and m2 = 4 kg are connected by a rope through a solid disk pulley with mass M = 2.5 kg and radius R = 0.2 m (I = (½)MR?). The rope is massless and doesn't slip of the %3D pulley. When released from rest, blocks start to move with constant acceleration. Find the magnitude of acceleration of the blocks. Hints: Select the direction of motion to set the positive/negative directions. Draw free-body diagrams for blocks 1 and 2. Express the torque on the pulley in both angular and linear terms to relate the tensions to rotation inertia and angular acceleration. Use that for the equations you obtained from free-body diagrams.

Current Attempt in Progress In an automatic clothes drier, a hollow cylinder moves the clothes on a vertical circle (radius r = 0.516 m), as the drawing shows. The appliance is designed so that the clothes tumble gently as they dry. This means that when a piece of clothing reaches an angle of 0 above the horizontal, it loses contact with the wall of the cylinder and falls onto the clothes below. How many revolutions per second should the cylinder make in order that the clothes lose contact with the wall when 0 = 57.0°?

A 270-g mass hangs from a string that is wrapped around a pulley, as shown in the figure. The pulley is suspended in such a way that it can rotate freely. When the mass is released, it accelerates toward the floor as the string unwinds. Model the pulley as a uniform solid cylinder of mass 1.00 kg and radius 7.00 cm. Assume that the thread has negligible mass and does not slip or stretch as it unwinds. Determine the magnitude a of the pulley's angular acceleration. rad/s? a = Determine the magnitude of the acceleration a of the descending weight. m/s?

You are swinging a 0.25 kg water balloon vertically. The distance from your shoulder (acting as the center of rotation) and the water balloon is about 0.65 m. You estimate the water balloon is traveling at 7.0 m/s. At the very top of the circular path, how much force is your hand holding the water balloon? Enter absolute value. Hint: the water balloon is experiencing uniform circular motion.
A spherical glass bead of mass M and radius R is releasedfrom rest at the top of an inclined track (angle  with thehorizontal) that ends in a curved section of radius r. Theglass bead rolls down the incline without slipping; there isfriction between the ramp and the glass bead. The momentof inertia of the glass bead is I = 2/5 MR2 Draw a force diagram for the glass bead on the ramp.Label all forces clearly Determine the linear acceleration of the marble when it is rolling down the incline. Your answer will be interms of theta and g . Determine the speed of the marble at the lowest point of the incline in terms of H and g.
In the figure below, block 1 has mass m1, block 2 has mass m2 and the shape pulley cylindrical, which is mounted on an axis perpendicular to the plane of the paper with friction negligible, has mass M and radius R. . When the system is released from rest, block 1 falls without the rope slipping on the pulley edge. From this, determine the magnitude of the acceleration of the blocks.
