SUMMARY
The discussion focuses on calculating the angular velocity of a motor that starts at 60 RPM and comes to rest after 10 revolutions, with its angular velocity decreasing linearly with angular displacement. The formula for angular velocity is established as ω(θ) = ω₀ - Cθ, where ω₀ is the initial angular velocity. To find the constant C, it is noted that the angular velocity reaches zero after 10 revolutions, necessitating conversion to radians for accurate calculations. The next step involves differentiating the angular velocity function with respect to θ to relate it to the time derivative of angular velocity.
