The slotted arm revolves in the horizontal plane about the fixed vertical axis through point o. the 2.5-lb slider c is drawn toward o at the constant rate of 2.7 in./sec by pulling the cord s. at the instant for which r = 7.9 in., the arm has a counterclockwise angular velocity Ο = 5.5 rad/sec and is slowing down at the rate of 2.4 rad/sec2. for this instant, determine the tension t in the cord and the force n exerted on the slider by the sides of the smooth radial slot. the force n is positive if side a contacts the slider, negative if side b contacts the slider.
