use the units given and the Gravitational Constant, G = 6.67 ×10−11 m3/kg/s^2.What is the force of gravity due to the Earth on a 52.0 kg ASTR 110 student standing on the equator dur- ing Spring Break. DATA: Equatorial radius of the Earth 6.378×106 meters; mass of the Earth 5.98 × 1024 kg.

32. At a given point above the surface of the Earth, the gravitational acceleration is equal to 5.4 m/s². Take the Earth mass M = 5.97x1024 kg and radius R = 6378 km. The altitude of this point, above the surface of the Earth, in km, is closest to: 33. What does the scale read? (Hint: t = rxF) a. 6900 b. 2800 C. 4200 d. 5700 e. 2200 a. b. C. d. a. b. C. d. e. C. 34. A solid cylinder of 5 cm radius is positioned on a frictionless plane inclined at 30 degrees above horizontal. A force F is exerted by a string wrapped around the spool. When F has a certain critical value the center of mass of spool does not move. When this is the case, what is the angular acceleration of the spool?

The orbit of Earth’s moon has a period of 27.3 days and a radius (semi-major axis) of 2.57 ×10-3 A.U. = 3.85 × 105 km. What is the mass of Earth? What are the units?

what are the magnitude and direction of the gravitational force exerted on Moe by 11.lf Moe exerts a gravitational force of 3.65 x 10-8 N on Larry, who is standing east of him, 10.If an object on the earth experiences a gravitational force of 25 N toward the center of the earth, what are the magnitude and direction of the force the object exerts on the earth? Larry? If each man has a mass of 70.0 kg, how far apart are they standing? If Curly were to bump into Moe, knocking him halfway to Larry, how would the new gravitational force between Moe and Larry compare to the original? a. ¼ as great b. ½ as great c. the same d. twice as great e. four times as great
