The Displacement D (In Meters) of an Object at Time $d = - 2 \sin ( 5 t )$

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?
- $d = - 2 \sin ( 5 t )$

A) simple harmonic; $- 2 \mathrm {~m} ; 5 \pi \mathrm { sec } ; \frac { 5 } { \pi }$ oscillations/sec
B) simple harmonic; $2 \mathrm {~m} ; \frac { 2 } { 5 } \pi \mathrm { sec } ; \frac { 5 } { 2 \pi }$ oscillations/sec
C) simple harmonic; $2 \mathrm {~m} ; \frac { 5 } { 2 \pi } \mathrm { sec } ; \frac { 2 } { 5 } \pi$ oscillations/sec
D) simple harmonic; $- 2 \mathrm {~m} ; \frac { 2 } { 5 } \pi$ sec; $\frac { 5 } { 2 \pi }$ oscillations/sec
