How Does Gravity Affect the Acceleration Between Two People?

[bigman8424]

how does this look, fun prob., need help on the 2nd part:

wat is the force that a 60 kb girl has on a 75 kg man, when they are 50 cm apart:

f = GM1m2/R2 = F = (6.67e-11)(75)(60)/(.50)^2
= 1.2e-6 N

second part:
how fast will man accelerate towards girl??

same formala?

What's the relationship between the force and the acceleration (assuming constant mass) ?You'll see it's only a simple division.Oh,and that 60Kg girl is fat...

To calculate the acceleration, we need to use Newton's second law which states that F = ma, where F is the force, m is the mass, and a is the acceleration. So, using the same formula from before, we can solve for a by rearranging the equation to a = F/m. Plugging in the values from the first part, we get a = (1.2e-6 N)/(75 kg) = 1.6e-8 m/s^2. This means that the man will accelerate towards the girl at a rate of 1.6e-8 meters per second squared.
