... Put the origin at the top of the device, where it is supported, so the initial y is –0.27 m: y new = ( – 0.27 m ) + ( – 3.96 m/s ) ( 10 –3 s ) = – 0.27396 m The unstretched length is 0.20 m, so the final stretch is 0.07396 m. If you use the initial velocity instead of the new velocity, the result is ...
