Based on past AP Physics 1 rubrics for similar problems:
Every point on a rigid rotating disk shares the same angular displacement over the same time interval. Therefore, ladybugs at different distances from the center have the same angular speed ). However, their linear (tangential) speed ) differs because it is defined by
Max ω (constant speed, no α): Set m r ω_max² = μ_s m g → ω_max = √(μ_s g / r) = √(0.40×9.8 / 0.12) = √(3.92/0.12) = √32.67 ≈ 5.72 rad/s.
(b) Determine the magnitude and direction of the acceleration of the ladybug at the new position.
Pay close attention to whether the disk is "driven by a motor" (constant ) or "rotating freely" (conserved
