Question

The radius of circle, the period of revolution, initial position and sense of revolution are indicated in the fig.

y- projection of the radius vector of rotating particle P is:

• A. \(y(t)=-3 cos2\pi t\), where \(y\) in \(m\)
• B. \(y(t)=4 sin(\frac{\pi t}{2})\), where \(y\) in \(m\)
• C. \(y(t)=3cos(\frac{3\pi t}{2})\), where \(y\) in \(m\)
• D. \(y(t)=3cos(\frac{\pi t}{2})\), where \(y\) in \(m\)

Answer 1

The Correct Option is D

The correct option is (D) :\(y(t)=3cos(\frac{\pi t}{2})\), where \(y\) in \(m\)
