If two springs S1 and S2 of force constants k1 and k2, respectively, are stretched by the same force, it is found that more work is done on spring S1 than on spring S2.

Statement 1 : If stretched by the same amount, work is done on S1, will be more than that on S2

Statement 2 : k1 < k2

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?

Two springs with spring constants k1 and k1 are connected toeach
other in series, end to end. The top of the first spring isattached to the ceiling and the second
string is connected and hanging below the first spring. A mass M isconnected to the bottom of
the second spring. The acceleration of gravity is g . Answer thefollowing in terms of quantities
given or a subset thereof.

(a) Derive an expression for the effective spring constant of thespring system?
(b) As the mass hangs vertically and sits motionless what is thedistance beyond equilibrium
that the system is stretched?
(c) What is the frequency of the small oscillations of thesystem?
(d) What is the period of the small oscillations.
(e) If the mass were doubled by what factor would the period of thesmall oscillations
change?

Consider two antennas radiating 6.4 MHz radio waves in phase witheach other. They are located at points S1 and S2, separated by adistance d = 175 m, Fig. What are the farthest two points on thepositive y axis where there will be destructive interference?(Destructive interference in this case means that a radio receiverplaced at that point would pick up no signal). farthest y 1 m
Second farthest y 2 m
