At the instant shown below, the bucket of the backhoe traces a path defined by r = 25 sin 0 ft, where 8 is in radians. When the bucket is at 0 = 100°, its angular velocity is 1.8 rad/s and its angular acceleration is Ö = -0.4 rad/s2. Answer the following questions. What is the radius, r, at this instant? Show your work. Magnitude rounded to 3 sig. fig. Units b. What is ve at this instant? Show your work. Units 7-400 ft = fe= 390 ft B

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
