2. A rope connect two masses, M₁-8 kg. and M₂-5 kg. They are initially held at the same height above the ground, h=1.5 m, with the left (larger) mass connected by a spring to the ground. When the masses are released, M₁ goes down 25 m, and M₂ goes up 25 m The spring is initially uncompressed. Both masses are initially and finally at rest. The objective of this problem is to find the value of k for this spring using conservation of energy
Simple harmonic motion
Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards the mean position. We see many examples of SHM around us, common ones are the motion of a pendulum, spring and vibration of strings in musical instruments, and so on.
Simple Pendulum
A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.
Oscillation
In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion takes place. In mathematics, oscillations can also be described as vibrations. The most common examples of oscillation that is seen in daily lives include the alternating current (AC) or the motion of a moving pendulum.
