Rotational Motion Bookwork Assignments

#1 Rotational Kinematic Practice Problems Page 311 Section 8.1 1, 2, 3, 8-13,15, and16 #2 (express your answer in rad/s for ω) #10 (Find linear acceleration, radius, rotational position, and the arc length) #11 (Find all of the following (not just three): linear acceleration, rotational acceleration, rotational velocity, and time) Remember that rotations per minute (rpm) is one rotation around a circle (2π) per 60 seconds Note: 1 mi = 1609 m

#2 Torque/Newton’s 2nd Law assignment Pg. 266 (1, 4) 310 (15,16 and 18) Pg. 311-312 (18-21, 25 (a is .1m), 28-31) Consider this question 32! 32a. Where is the axis of rotation of the sign above to the right. 32b. Explain what has to be true for this awning not to “rotate” and swing down. 32c. The 2.5 meter long awning to the right weighs 225 N and is supported by two identical support bars (not pictured). The angle between the support bars and the awning is 37 degrees and the center of mass is located .5 meters from the axis of rotation. Calculate the Force supplied by EACH support bar and the total torque created by BOTH support bars.
