question 44

Multiple Choice

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?
- $$d = 8 + 2 \sin ( 2 \pi t )$$

• 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; \(2 \mathrm {~m} ; \frac { 1 } { 2 }\) sec; 2 oscillations/sec
