The slider P in the image below has a constant velocity of 2.6 m/s to the left. Calculate the angular velocity w of link OA at the instant when 43° as shown, expressing your answer to one decimal place, in units of rad/s (but do not include the units in your answer). Use a sign convention that anticlockwise is positive (ie if you calculate 15.359 rad/s CW, your answer should be -15.4, and if CCW, 15.4). A 9cm 4cm P Ө 0
