Transcript of Simple Harmonic Motion (SHM)
1. Period, T, the time it takes to execute one complete cycle of motion. Units:
2. Frequency, f, the number of cycles or vibrations per unit time. Units:
3. Amplitude, A, the maximum distance traveled by an object away from its equilibrium position. Units:
An object is attached to a spring and executes SHM with a period of 0.25 s. If the spring constant of the spring is 126.3 N/m then what is the mass of the object?
A 1300 kg car is constructed on a frame supported by four springs. Each spring has a spring constant of 20,000 N/m. If two people riding in the car have a combined mass of 160 kg, find the:
a) Period of the vibration of the car when it is driven over a pothole in the road.
b) Frequency of the vibration of the car.c) How long does it take the car to execute 3 complete
cycles?
