The Displacement D (In Meters) of an Object at Time $$d = 8 + 2 \sin ( 2 \pi t )$$

The displacement d (in meters) of an object at time t (in seconds) is given. Describe the motion of the object. What is the
maximum displacement from its resting position, the time required for one oscillation, and the frequency?
- $$d = 8 + 2 \sin ( 2 \pi t )$$

A) simple harmonic; $- 2 \mathrm {~m} ; 1 \mathrm { sec } ; 1$ oscillation/sec
B) simple harmonic; $2 \mathrm {~m} ; 1 \mathrm { sec } ; 1$ oscillation/sec
C) simple harmonic; $8 \mathrm {~m} ; 1 \mathrm { sec } ; 1$ oscillation/sec
D) simple harmonic; $2 \mathrm {~m} ; \frac { 1 } { 2 } \mathrm { sec } ; 2$ oscillations/sec
