Two identical spiral springs have mass m1 on the one and m2 on the other. It is found that the spring with mass m1 oscillates with one and five-ninths the period of the other spring. Find the ratio of the masses (m2/m1).
Two ice skaters have masses m1 and m2 and are initially stationary. Their skates are identical. They push against one another, as in Figure 7.10, and move in opposite directions with different speeds. While they are pushing against each other, any kinetic frictional forces acting on their skates can be ignored. However, once the skaters separate, kinetic frictional forces eventually bring them to a halt. As they glide to a halt, the magnitudes of their accelerations are equal, and skater...
3. A block of a mass 500 g is connected to two springs as shown in the picture. The spring constant of one of the springs is 1000 N/m. The block oscillates on a frictionless surface with frequency 30 Hz. Find force constant of the other spring. n u lana light rod oscillates at a r
A small mass m1 is supported by a vertical spring. When an additional mass m2 = 113 g is attached to the original mass, the system begins to oscillate at a frequency of 0.500 Hz. When the oscillations die out, the spring is found to have increased in length by Δy = 8.00 cm. Find the mass m1.

Two blocks ona horizontal frictionless surface, one with mass m1, and one with mass m2 have a compressed spring in between them. The potential energy of the spring is E. Suppose the spring is allowed to decompress so that it has no potential energy, and the blocks have gained that energy in the form of kinetic energy. What is the final speed of each of the two blocks?
A single mass m1 = 4.4 kg hangs from a spring in a motionless elevator. The spring is extended x = 14 cm from its unstretched length. Now, three masses m1 = 4.4 kg, m2 = 13.2 kg and m3 = 8.8 kg hang from three identical springs in a motionless elevator. The springs all have the same spring constant that you just calculated above. 1) What is the force the top spring exerts on the top mass? 2) What...
Two blocks of mass m1 and m2 > m1 are drawn above. The block m1 sits on a frictionless inclined plane tipped at an angle θ with the horizontal as shown. Block m2 is connected to mı by a massless unstretchable string that runs over a massless, frictionless pulley to hang over a considerable drop. At time t = 0 the system is released from rest. a) Draw a force/free body diagram for the two masses. b) Find the magnitude of the...
You have two equal masses m1 and m2 and a
spring with a spring constant k. The mass m1 is
connected to the spring and placed on a frictionless horizontal
surface at the relaxed position of the spring. You then hang mass
m2, connected to mass m1 by a
massless cord, over a pulley at the edge of the horizontal surface.
When the entire system comes to rest in the equilibrium position,
the spring is stretched an amount d1 as shown...
Now, three masses m1=3.4kg, m2=10.2kg and m3=6.8kg x=14 hang from three identical springs in a motionless elevator.
