Question

A 4-kg block extends a spring by 16 cm from its unstretched postion .The block is removed and a 0.5 -kg boby is hung from the same spring If the spring is then stretched and released , what is the time period of oscillations of the mass suspendrd ? What is the force constant of the spring ?

Answer 1

Answer:

force constant of the spring is 2.5 N/m

Explanation:

when hanging 4kg on spring it extend 16 cm

kx = mg

k16 = 40

k = 2.5N/m
