The particle has a mass of 0.7 kgkg and is confined to move along the smooth horizontal slot due to the rotation of the arm OAOA. Assume the particle contacts only one side of the slot at any instant. The arm has an angular acceleration of θ¨θ¨ = 3 rad/s2rad/s2 when θ˙θ˙ = 2 rad/srad/s at θθ = 30∘∘. Determine the magnitude of the force of the rod on the particle when θ = 30∘. Determine the magnitude of the normal force of the slot on the particle when θ= 30∘
