Question

The radius of circle, the period of revolution, initial position and sense of revolution are indicated is the figure.

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

y(t) = 4sin$\left( {{{\pi t} \over 2}} \right)$, where y in m

y(t) = 3cos$\left( {{{3\pi t} \over 2}} \right)$, where y in m

y(t) = 3cos$\left( {{{\pi t} \over 2}} \right)$, where y in m

y(t) = -3cos2$\pi $t, where y in m
