Question

100kg car mass, constant springs at 17.5 kN/m. This piece of crap with a magnetic hanger, was dropped into the dump. Once it hits the ground, it oscillates. Calculate frequency vibrations

Answer 1

$w= \sqrt{k/m} ​$

$\sqrt{17500/100} = 13.299 rads/sec$

$w = 2\Pi f$

$f = 13.229/2\Pi$

$= 20.779Hz$
