- A pulley with moment of inertia I = 0.75 kg-m² and radius R = 15 cm is mounted on a wall. A light string is wrapped around the pulley with a mass m = 2.0 kg attached to the end. The pulley rotates as the mass falls. Use Newton's second law to calculate the acceleration of the mass. Check that your formula gives the expected behavior when I →0. => To help get started, the free body diagrams m and the pulley is shown below. T m Write down Newton's second law for each diagram. Use (and explain) the relationship R a = RO TIL R T3 1. A uniform solid sphere rolls without slipping down a 28° inclined plane. What is the acceleration of the sphere's center of mass? The moment of inertia of a uniform solid sphere about an axis that passes through its center = mr².

- Computation. A uniform solid sphere has mass M = 8.9 kg and radius R = 0.2 m. What is its moment of inertia about an axis tangent to its surface? I- 2 kg .m² Record your your numerical answer below, assuming three significant figures. Remember to include a as necessary.1. Rotational Mechanics and the Atwood's Machine. Consider an Atwood's machine, with two different masses, m1=1.0 kg and m2=2.0 kg suspended from a uniform solid disk pulley with mass = 1.0 kg, by a string passing over the pulley. The pulley has radius r = 10cm and a moment of inertia about its axis of rotation. The string does not slip on the pulley when the masses are released from rest. a) Find the acceleration of the system. b) How does the mass of the pulley impact the acceleration of the system (i.e. would the acceleration be more, less, or equal if ignored)? 2.A large grinding wheel in the shape of a solid cylinder of radius 0.330 m is free to rotate on a frictionless, vertical axle. A constant tangential force of 280 N applied to its edge causes the wheel to have an angular acceleration of 0.946 rad/s2. What is the moment of inertia of the wheel? What is the mass of the wheel? If the wheel starts from rest, what is its angular velocity after 5.40 s have elapsed, assuming the force is acting during that time?
