CHECK MY ANSWERS??? 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? I'm not sure, but I got -2? b. what is the object maximum displacement(in meter) from its t=0 position? 3? c. how much time(in sec) is required for one oscillation? I got 1/4 sec? d. what is the frequency(measured in Hz) of this oscillation Not too sure how to do this...

Frequency is the measure of one cycle ( peak to peak or trough to trough).
