3B. A 0.300 kg mass is initially held at rest against a compressed spring with a spring constant of 500 N/m. The system is situated such that the mass is on a frictionless, horizontal surface and the spring acts parallel to the surface. a) If the mass leaves the spring with a speed of 20.0 m/s, by how much was the spring initially compressed? b) What is the speed of the mass when the spring is halfway back to its equilibrium position?
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.
