A platform of mass 0.8 kg is supported on four springs (only two springs are shown in the picture, but there are four altogether). A chunk of modeling clay of mass 0.6 kg is held above the table and dropped so that it hits the table with a speed of v = 0.9 m/s.
The clay sticks to the table so that the the table and clay oscillate up and down together. Finally, the table comes to rest 6 cm below its original position.
-->What is the effective spring constant of all four springs taken together?
i did the following: F = kx
so F/x = k
i'm thinking the only force contributing to this is dropping (force) of the modeling clay on the platform. or does the weight (gravity) of the platform contribute to any of this?
