Please solve correctly using F$=$ma and r$-$theta coordinates. The forked rod is used to move the $5-lb$ particle around a smooth, horizontal path given by $r=(2+cos)ft.$ It rotates by $=(0\mathrm{.}5t^2)$ radians $($where $t$ is in seconds$).$ At $=60($i$.$e$.\frac{}{3}$rad $),$ determine the force of the rod on the particle and the normal force of the path on the particle $($use $F=ma,r-$ coords$).$
