## anonymous 4 years ago an objects motion is describe by the equation d=3sin(8pi t)-2. the displacement d is measured in meter. the time t is measured in seconds. a. what is the object position (in meter)at t=0? b. what is the object maximum displacement(in meter) from its t=0 position? c. how much time(in sec) is required for one oscillation d. what is the frequency(measured in Hz) of this oscillation

in this equation $\omega=8\pi$ a) d=0 b)3 c)$\theta=\omega t$ for 1 oscilation t=T & theta=2pi so it yields T d)$\omega=2\pi \nu$
