The slot in the fixed block A has a 15 inclination. Pin P is free to translate within the slot. The position of P is controlled by the rotation of slotted arm B, which rotates about the pivot at O. At the instant shown, 0 = 30, w 1 rad/sec (constant), and the distance = r = OP is 4". Find , r, and the speed and acceleration of pin P at this instant. Hint: Use both r-0 and Cartesian coordinates (or r-0 and n-t coordinates). 4" B A 15
