Asked by Cam
A single mass (m1 = 3.2 kg) hangs from a spring in a motionless elevator. The spring constant is k = 253 N/m.
1)
What is the distance the spring is stretched from its unstretched length?
This first answer is equal to 12.4 cm but I am having trouble on the second question...
2)Now, three masses (m1 = 3.2 kg, m2 = 9.6 kg and m3 = 6.4) hang from three identical springs in a motionless elevator. The springs all have the same spring constant given above.
-->What is the magnitude of the force the bottom spring exerts on the lower mass?
If anyone could help me out with this number 2 I would appreciate it. Thank you.
