3. A simple pendulum of length 2.00 m is made with a mass of 2.00 kg. The mass has a speed of 3.00 m/s when the pendulum is30.0° above its lowest position. What is the speed of the mass when the pendulum is 45.0° above its lowest position? 4. Two parakeets sit on a swing with their combined centre of mass 12.0 cm below the pivot, in a simple pendulum system. a. At what frequency do they swing? b. What is the swinging frequency when one parakeet suddenly falls from the swing, with the centre of mass of the other parakeet remaining 12 cm below the pivot? c. If the speed of the parakeet is 2 m/s when they pass through the equilibrium position, find the swinging amplitude of this system
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.
