Homework Statement
Calculate the maximum gravitational attraction between a man and an apple, when a) the apple was 1m from the man's center of mass, b) the apple hit his head. (man's mass 60kg, apple mass 100g)
Homework Equations
F=G(m_1)(m_2)/r^2
F=ma
The Attempt at a Solution
I set up the problem using the first equation F=((6.67x10^-11)*(60kg)*(0.1kg))/1 meter which came out to 4.002*10^-10. And for when the apple hit his head I got zero because F=((6.67x10^-11)*(60kg)*(0.1kg))/0. I guess my first question is would there be no gravitational attraction between the apple and the man when they are in contact? Does the gravitational attraction now become a weight force and normal force that cancel out?
