Determine the force of the rod on the particle and the normal force of the Isot on the particle when 0 = 30°. The rod is rotating with a angular velocity of ė = 2rad/s and an angular acceleration of = 3rad/s². Assume the particle only contacts one side of the slot at any instant. To check your answer, please enter the normal force of the slot onto the particle in Newtons.
