Homework Help: SHM Platform Problem

  1. Sep 17, 2008 #1
    Hey all,

    I trying to get somewhere with the following problem and am not having much luck. Any tips or suggestions would be appreciated! I found that the block leaves the platform at y=2.5 cm though.

    A platform is in SHM in the vertical direction with an amplitude of 5cm and freq. of 10/pi vibrations/sec. A block is put on the platform at the lowest point of its path. How far will the block rise above the highest point reached by the platform?

    Thanks!!

    How fast is the block going when it separates from the platform? Where will it separate from the platform? Then it's a trajectory problem.

    Okay, so I've found that the velocity at that time (0.05291) is -0.8715. I know that the displacement in y is 2.5 cm. I'm not quite sure how'd it proceed from here though.

    What is that calculation that gave you the numbers?
