1.	A block of 0.5kg is placed on a horizontal platform. The system is making vertical oscillations about a fixed point with a frequency of 0.5Hz. Find the maximum amplitude of oscillation if the block does not lose contact with the horizontal platform?
Answer» Solution :At the highest point i.e., upper extreme POSITION, APPARENT weight of the block `= MG -m omega^2 A `. When it just does contact, mg`-m omega^2 A = 0, A= g//omega^2`
