Mamut is standing in the lunch line 6.38 x 106m from the center of Earth. Earth’s mass is 5.98 x 1024kg. What is his acceleration due to gravity?
1. Mamut is standing in the lunch line 6.38 x 106m from the center of Earth. Earth’s mass is 5.98 x 1024kg. What is his acceleration due to gravity?
2. A 3.25 x 1019kg space station has a gravitational acceleration of 4.1 m/s/s from Earth. How far away is the space station?
3. Suppose that two objects attract each other with a gravitational force of 20 units. If the distance between the two objects is halved, what is the new force of attraction between the two objects?
4. Fred is very concerned about his weight but seldom does anything about it. After learning about Newton's law of universal gravitation in Physics class, he becomes all concerned about the possible effect of a change in Earth's mass upon his weight. During a (rare) free moment at the lunch table, he speaks up "How would my weight change if the mass of the Earth increased by 10%?" How would you answer Fred?
