Problem
A 1 kg block attached to a spring vibrates with a frequency of 1 Hz on a frictionless horizontal table. Two springs identical to the original spring are attached in parallel to an 8 kg block placed on the same table. So, the frequency of vibration of the 8 kg block is:
(1) 41 Hz
(2) 221 Hz
(3) 21 Hz
(4) 2 Hz
