Question
The diagram below represents a setup for demonstrating motion.
Lever
Compressed spring
Support rod
A
B
Support base
Tabletop
When the lever is released, the support rod withdraws from ball B, allowing it to fall. At the same instant,
the rod contacts ball A, propelling it horizontally to the left. Which statement describes the motion that is
observed after the lever is released and the balls fall? [Neglect friction.]
(1) Ball A travels at constant velocity.
(2) Ball A hits the tabletop at the same time as ball B.
(3) Ball B hits the tabletop before ball A.
(4) Ball B travels with an increasing acceleration.
