Annaliese (55.0 kg) stands on the top of Mount Everest a. If her force due to gravity is 537.5N, how high is Mount Everest? (remember d in the equation is from the center of the earth Radius earth = 6.38 x 106 m) b. What is the acceleration due to gravity she is experiencing? Does this make sense? Explain
11) Newton's Law of Gravity says that the force of gravity between any two objects is G d2 where the m's are the masses of the objects and, d is the distance between them, and G is a constant that depends on your choice of units. This includes big things like planets and small things like you and your pets. We don't need to know the values of the masses to think about what happens as two objects approach each other! lim G d--0+ d? If you think too long about your answer, it may be a bit troubling. What does it say about the force of gravity when you actually touch your pets?
