5.) a.) An asymmetric object is free to rotate within the plane of the page about an axis through point A. Use the right-hand rule to determine the direction of the torque on the object for each of the four (4) labelled forces. (Ans. 1: CCW, 2: None, 3: CCW, 4: CW.) A. b.) A constant 25.0 N force acts on a string wrapped around a solid disk (R = 8.5 cm). The disk rotates without translating. The linear acceleration of the string is 1.50 m/s. What is the moment of inertia of the disk? (Ans. / 0120 kg m².) 1.50 m/s² 25.0 N c.) A yo-yo consists of a solid uniform disk (mass M. radius R) wrapped with a light string. It is let go from rest with the end of the string held stationary. Use Newton's 2 law of motion to find the linear acceleration of the disk as it unravels. Assume the string does not slip as it unravels. (Ans. a -(²/3)9) dd,
Gravity & Satellite Motion 6.) a.) Far out in space, a mass m is placed between masses A and B, all arranged along a straight line. The net gravitational force on mass m is zero. Find the separation distance between m and A (Ans. r=0.97m.) MA= 5.50 kg PO 1.20 m m = 8.40 kg b.) Venus orbits the sun with a period of 225 days and a centripetal acceleration of 0.0113 m/s Determine the orbital radius and orbital speed. (M. 1.99 x 10 kg. G=6.67 x 10 Nm²/kg) (Ans. = 1.08 x 10 m, v=3.51 x 10¹ m/s = 35.1 km/s.) c.) Astronomers detect two planets, A and B, orbiting a distant star. Both planets orbit counterclockwise. Their first image is shown on the left; the image taken two months later is on the right. What are the orbital periods of the planets expressed in years, and what are their semi-major axes expressed in AUS? (Ans. TA-0.667 yr. r=0.763 AU, Ts 0.222 yr, f-0.367 AU.) *
