Question

ASSIGNMENT 7.1
A 2.0 kg block hung from a vertical spring causes it to stretch by 20.0 cm. If
the 2.0 kg block is replaced by a 0.50 kg mass, and the spring is stretched and
released, what are the frequency and period of the oscillations?
(2.2 Hz & 0.45 s)​

Answer 1

Explanation:

k = F Applied/x = (2.0 kg)(9.8 m/s2)/(0.20 m) = 98 N/m.  

f = w/2p = 2.2 Hz.  

T = 1/f = 0.45 s.
