1. What is the spring constant? 2. What is the amplitude of the oscillation? 3. What is the frequency of the oscillation? https://session.masteringphysics.com/myct/itemView?offset-next8a General Physics II CH 14 HW Problem 14.22 Inc Problem 14.2 2 A 50-cm-long spring is suspended from the ceiling. A 310 g mass is connected to the end and held at rest with the spring unstretched. The mass is released and falls, stretching the spring by 14 cm before coming to rest at its lowest point. It then continues to oscillate vertically Part B What i Expre Sub Inc Part C What

Explanation / Answer

a)

Change in Potential energy =Kinetic energy

mgx=(1/2)Kx2

0.31*9.8*0.14=(1/2)*K*0.142

K=43.4 N

b)

Amplitude

A=14/2=7 cm

c)

frequency

f=1/2pi*sqrt[K/m]=(1/2pi)*sqrt[43.4/0.31]

f=1.88 Hz
