1984 Ap Physics B Free Response Answers Verified

The 1984 AP Physics B Free Response questions cover core topics including vertical circular motion, momentum and collisions, and radioactive decay. Below are summaries and key answers for the primary problems from that year's exam. 1984 B1: Vertical Circular Motion A ball of mass attached to a string of length moves in a circle. At the top of the path, the tension is Net Force at the Top The net force cap F sub n e t end-sub consists of both gravity ( ) and tension ( ) acting downward toward the center. . The direction is downward. Speed at the Top ( Set the centripetal force equal to the net force: Time to Reach Ground If the string is cut at the top, the ball is at a height
