I am given the answers just need help with the equations.
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.) *
