You find that if you hang a 1.95 kg weight from a vertical spring,it stretches 5.65 cm.

a.What is the force constant of this spring in N/m?
b. How much mass should you hang from the spring so it will stretchby 9.53 cm from its original, unstretched length?

You hang a mass of 10 kg from a spring having force constant of 500 N/m. Find the extension in the spring?

A single mass m1 = 4.5 kg hangs from a spring in a motionless elevator. The spring is extended x = 15 cm from its unstretched length.
 
1)What is the spring constant of the spring?
 
Now, three masses m1 = 4.5 kg, m2 = 13.5 kg and m3 = 9 kg hang from three identical springs in a motionless elevator. The springs all have the same spring constant that you just calculated above.
 
2)What is the force the top spring exerts on the top mass?
 
3)What is the distance the lower spring is stretched from its equilibrium length?
 
4)Now the elevator is moving downward with a velocity of v = -2 m/s but accelerating upward with an acceleration of a = 3.8 m/s2. (Note: an upward acceleration when the elevator is moving down means the elevator is slowing down.)
 
What is the force the bottom spring exerts on the bottom mass?
 
5) What is the distance the upper spring is extended from its unstretched length?
 
6) Finally, the elevator is moving downward with a velocity of v = -2.5 m/s and also accelerating downward at an acceleration of a = -2.2 m/s2.
 
The elevator is:
 
speeding up
 
slowing down
 
moving at a constant speed
 
7) Rank the distances the springs are extended from their unstretched lengths:
 
x1 = x2 = x3
 
x1 > x2 > x3
 
x1 < x2 < x3
 
8) What is the distance the middle spring is extended from its unstretched length?

The force constant of a spring is 137 N/m. Find the magnitude of the force required to

(a) compress the spring by 4.80 cm from its unstretched length and

(b) stretch the spring by 7.36 cm from its unstretched length.
