A spring is hung from the ceiling. A 0.300 kg block is then attached to the free end of the spring. When released from rest, the block drops 0.170 m before momentarily coming to rest.

Question

(a) What is the spring constant of the spring?

(b) Find the angular frequency of the block's vibrations.

Answer 1

a) F=-kx => k=F/x => k=mg/.5x

.300kg(9.8)/.5(.170m)= k

b) w=squareroot(k/m)
