Equation of SHM is `y=3sin60pit`. Calculate its amplitude, time period and acceleration at its position of maximum displacement.

Text Solution

Verified by Experts

Comparing the given equation with `y=Asinomegat`,
we get, amplitude, A = 3 units , `omega=60pi`.
`therefore" "` Time period, `T=(2pi)/omega=(2pi)/(60pi)=1/30s`
`therefore" "` Acceleration at its position of maximum displacement
`=omega^(2)A=(60pi)^(2)xx3=1.065xx10^(5)"unit"*s^(-2)`.
