Question

when the displacement is 0.04.
A block weighing 4.0 kg extends a spring by 0.16 m from its un-
stretched position. The block is removed and a 0.50 kg body is hung
from same spring. If the spring is now stretched and then released,
what is its period of vibration?
(T = 0.28 s)
​

Answer 1

Answer:

I don't understand this question

Answer 2

Answer:

The spring constant can be found out by

k=

0.16

N/m=250N/m.

Time period T is given by

T=2π
