The slotted arm OA rotates about a horizontal axis through point O. The 0.20-kg slider P moves with negligible friction in the slot an controlled by the inextensible cable BP. For the instant under consideration, 0 = 39°, @= 0 = 3.5 rad/s, 0 = 0, and r = 0.67 m. Determine the corresponding values of the tension T in cable BP and the force reaction R perpendicular to the slot. The force R is positive if the contact comes from the lower edge of the slot and negative if the contact comes from the top edge.
