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

question 3

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

• 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

Definitions:

Error Variable

The error variable represents the component of randomness or unexplained variance in a statistical model, distinguishing between the observed and predicted values.

Probability Distribution

A mathematical procedure that assesses the likelihood of different experiment outcomes.

Random Error Term

Refers to the unpredictable and inevitable fluctuations or deviations in data or experimental results that cannot be attributed to the variables being studied.

Variance

A statistical measure that represents the average squared deviation from the mean, showing how data points are spread out.
