physics

$y(t) = -3 \cos (2\pi t),$ where $y$ is in m

$y(t) = 4 \sin (\frac{\pi t}{2}),$ where $y$ is in m

$y(t) = 3 \cos (\frac{\pi t}{2}),$ where $y$ is in m

Explanation

To solve this problem, we need to find the $y$ -projection of the radius vector of the rotating particle $P. \\$ Given: $\\$ • Radius of the circle $r = 3$ m. $\\$ • Period of revolution $T = 4$
