Question
A body of mass 1 kg is mafe to oscillate on a spring of force constant 16 N/m. Calculate (a) Angular frequency, (b) Frequency of vibrations.
Solution
Given:
m = 1kg
k= 16N lm
ω = ?
n = ?
Formula:
k=mω2
`therefore ω= sqrt k/m `
` ω = sqrt 16/1`
`therefore ω = 4 rad // s `
`therefore ω = 2 pi n `
`therefore n = ω/(2pi)= 4/ (2xx3.14)= 2/3.14= 0.636 Hz `
