29 **Title: Motion of Rolling Spheres on Cylindrical Surfaces****Problem Description:**18–29. A 10-lb sphere starts from rest at \( \theta = 0^\circ \) and rolls without slipping down the cylindrical surface, which has a radius of 10 ft. Determine the speed of the sphere’s center of mass at the instant \( \theta = 45^\circ \).**Diagram Explanation:**The provided image features a diagram illustrating a sphere rolling down a cylindrical surface. The main components and annotations in the diagram are:- A sphere representing the aforementioned 10-lb sphere, positioned initially at the topmost part of the cylindrical surface (\( \theta = 0^\circ \)).- The cylindrical surface perimeter is indicated with a semi-circular arc.- The sphere is shown in two positions: - At \( \theta = 0^\circ \) (topmost point). - At \( \theta = 45^\circ \), where it has rolled a certain distance down the cylindrical surface.- Radius indicators: - The total radius of the cylindrical surface (10 ft). - The radius marked from the surface to the sphere’s center of mass (\( 0.5 \) ft from the surface).- The angle \( \theta \) is depicted by a radial line originating from the cylinder’s center to the sphere’s center of mass.**Instructions for Students:**- Carefully observe the motion and forces acting on the sphere as it rolls down.- Apply principles of rotational dynamics and energy conservation to derive the velocity of the sphere’s center of mass.- Use mathematical equations relevant to potential and kinetic energy transformations.- Ensure to keep track of radius components, as the sphere rolls without slipping, affecting rotational inertia.**Learning Objectives:**- To understand how spherical bodies roll without slipping and the implications for kinetic friction forces.- To solve problems involving rotational motion on curved surfaces.- To apply the energy conservation principle in physical systems comprehensively.---This transcription serves as an educational aid, helping students visualize and understand the physics of rolling motion through guided problem-solving and analysis.
