question 45

Multiple Choice

A particle with a mass of 65 g is undergoing simple harmonic motion. At time t = 0, the particle is at its extreme positive displacement of 18.0 cm. The period of the motion is 0.600 s. At time t = 1.35 s, the velocity of the particle is

• A) -1.9 m/s
• B) zero
• C) 0.84 m/s
• D) +1.9 m/s
• E) -0.84 m/s

Definitions:

Cov (x,y)

Represents the covariance between two variables \(x\) and \(y\), measuring how changes in one variable are associated with changes in another.

Covariance

A statistical measure that indicates the extent to which two variables change together; if the greater values of one variable mainly correspond with the greater values of the other variable, and the same holds for the lesser values, the covariance is positive.

Slope

A measure of the steepness or incline of a line, representing the ratio of the change in the y-value to the change in the x-value.

Coefficient of Correlation

A statistical measure that computes the strength and direction of a linear relationship between two variables.
