In this activity, the students will try to slip a secret agent into a factory’s air duct. To do this, they have to determine the exact descent time of the platform the secret agent is standing on. The platform is attached to a cord, and the descent triggers the rotation of a radar antenna. The solution to the problem relies on the concepts of rotational dynamics.
