Introduction Newton's universal law of gravitation states that the force of attraction between two objects with masses M and m separated by a distance d has magnitude Mm d2 F=G where G is universal gravitational constant = 6.67 x 10'11 Nmzkg'z. Submit your answers using Blackboard. 1 Preliminary Question 1. Find the force of attraction between you and your friend. Assume you both have same mass of 90 kg and that you are 1.0 m apart. (N) 2. What is the value of G on Saturn? 3. What is the value of g on Saturn at the equator? (hint: find the equatorial radius and mass on wiki or another source) (III/52) The acceleration due to gravity 9 on Earth's surface is about 9.81 m/s2 4. What is g as experienced by an astronaut on the ISS, orbiting at average altitude of 415km? 5. What is the mass of a 75kg astronaut on the [35? (kg) 6. What is the weight (force) of a 75kg astronaut on the 188? (N)
