3. A car is traveling on a circular race track of radius R=300 ft. and is being tracked by a device located at the center of the track which can rotate and measure the angular velocity of the vector locating the car (treated as a particle). If the car's speed is 150 ft/s and is increasing at a rate of 15 ft/s°, what is the angular rotational speed of the vector tracking the car. What is the magnitude of the acceleration of the car. de/dt R S.60 402E
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.
