4. A 2-kilogram block is dropped from a height of 0.45 meter above an uncompressed spring, as shown above. The spring has a spring constant of 200 N/m and negligible mass. The block strikes the end of the spring and sticks to it. a. Determine the speed of the block at the instant it hits the end of the spring. +9=½v² 1.8=√²² (v = 1.34 16 m/s) U₂ = k mgh mu² b.

Is the speed of the block a maximum at the equilibrium position, explain. Yes, it is the point where spring. An instant earlier and it is still accelerating, loter it is decelerating there is no force being applied by the
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.
