1. The problem statement, all variables and given/known data A block attached to a spring underneath oscillates vertically with a frequency of 4Hz and an amplitude of 7.00cm. A tiny bead is placed on top of the block jut as it reaches its lowest point. Assume the bead's mass is so small that its effect on the motion of the block is negligible. At what distance from the block's equilibrium position does the bead lose contact with the block 2. Relevant equations Hooke's Law? 3. The attempt at a solution My first instict was that the bead would launch up until the maximum amplitude when the spring starts to move downward. Then I thought about Hooke's Law. Am I supposed to sum up the forces and say the bead is launched when there is no normal (restoring) force? This would mean the bead loses contact at equilibrium. Am I right about this?
