String and spring over block
The blue box in the figure has a mass of 38 kg. To the nearest newton, what is the tension in the rope?
If the spring has a spring constant of 515 N/m, to the nearest tenth of a cm how far is it stretched?

Solution Preview
Assuming the usual assumptions, that there is not friction, massless rope and spring, the rope must have the same tension T in all its parts. Therefore 2T from the two branches of the rope ...
Solution Summary
The solution assists with determining the tension in the rope and how far the spring constant has stretched.
Simple Harmonic Motion: Three problems
(See attached file for full problem description with symbols and diagrams)
1.) A block hangs in equilibrium from a vertical spring. When a second identical block is added, the original block sags by 6.00 .
Part A
What is the oscillation frequency of the two-block system?
2.) The figure is the velocity-versus-time graph of a particle in simple harmonic motion.
Part A
What is the position at
3.) A 90.0 mass on a 1.50 -m-long string is pulled 7.80 to one side and released.
Part A
How long does it take for the pendulum to reach 3.40 on the opposite side?
