The Displacement D (In Meters) of an Object at Time $$d = 4 \cos ( 5 t )$$

question 9

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?
- $$d = 4 \cos ( 5 t )$$

• A) simple harmonic; \(4 \mathrm {~m} ; \frac { 5 } { 2 \pi }\) sec; \(\frac { 2 } { 5 } \pi\) oscillations/sec
• B) simple harmonic; \(4 \mathrm {~m} ; 5 \pi \mathrm { sec } ; \frac { 5 } { \pi }\) oscillations/sec
• C) simple harmonic; \(- 4 \mathrm {~m} ; \frac { 2 } { 5 } \pi \mathrm { sec } ; \frac { 5 } { 2 \pi }\) oscillations/sec
• D) simple harmonic; \(4 \mathrm {~m} ; \frac { 2 } { 5 } \pi \mathrm { sec } ; \frac { 5 } { 2 \pi }\) oscillations/sec
