In what time after its motion begins, will a particle oscillating according to the equation, `y=7 sin 0.5 pi ` t move from the mean position to maximum displacement ?

Options

A. 0.5 s
B. 1.5 s
C. 1s
D. 2s

Answer

C

Explanation

`y = 7 sin 0.5 pit`
`omega = 0.5 pi`
`T = (2pi )/(omega) = (2pi)/(0.5 pi) = 4`
`t = (T)/(4) = (4)/(4) = 1s`
