Converting Between Linear & Rotational
9PRACTICE PROBLEM
A sphere attached to a rod is rotated, starting from rest, in a circular path of diameter d with a constant angular acceleration α. The sphere undergoes an angular displacement of θ2-θ1. Write the expressions of the sphere's linear velocity and radial acceleration in terms of d, α, and θ2-θ1.
