HW$10\mathrm{.}2-$ The pin $P$ is constrained to move in the smooth

curved slot, which is defined by $r=(0\mathrm{.}6cos(2))m.$ The

motion of the pin is controlled by the rotation of the slotted

arm $OA,$ which has a constant clockwise angular velocity of

$A{}^{}=-3ra\frac{d}{s}.$ When $P$ is located at $=15,$ find:

Values for $r,r^{},r^{},,{}^{},$ and ${}^{}$

The magnitude and direction of $v_r$ and $v_{}$

The magnitude of the $a_r$ and $a_{}$ components

On a set of $x-y$ axes, draw:

The direction of vec$(r)$

The direction of vec$()$

The direction of vec$(v)$

The direction normal to the path

Cylindrical components of acceleration, drawn as

vectors $($i$.$e$.$ an acceleration diagram$)$
