The amplitude and time period of a aprticle of mass `0.1kg` executing simple harmonic motion are `1m` and `6.28s`, respectively. Then its angular frequency and acceleration at a displacement fo `0.5m` are respectively

Options

A. `1 rad//s, 0.5 m//s^(2)`
B. `2 rad//s, 1 m//s^(2)`
C. `0.5 rad//s, 0.5 m//s^(2)`
D. `1 rad//s, 1 m//s^(2)`

Answer

A

Explanation

`omega = (2pi)/(T) = (2pi)/(6.28) = 1`
